My Menstrual Cycle Is Still Irregular Has The Pill Affected My Fertility

Kudlow: A strong ‘America First’ has turned into American weakness

Its unlikely the pill has caused any fertility problems, but it can sometimes cover up problems you already have, such as missing periods or PCOS .This is because the pill prevents the ovaries from releasing an egg , so although its normal to experience period-type bleeding on the pill, you dont have a real period.

Contact your GP if youre still having irregular periods 3 months after stopping contraception.

What Do I Need To Do To Prepare For My First Period

There is nothing in particular you need to do to prepare for your first period, besides having feminine hygiene products and over-the-counter pain relievers such as ibuprofen or naproxen on hand. If you happen to get your period with no access to menstrual products, toilet paper will work in an emergency. If you get your first period at school, your teacher or school nurse will have a pantiliner or pad on hand.

There are a variety of menstrual products available to you:

Disposable pads

These absorbent pads have an adhesive backing that sticks to the inside of your underwear. They are available in different lengths and absorbencies, and some have adhesive wings that wrap around the sides of your underwear. Disposable pads should be changed every 4-6 hours and are thrown out after a single use.


These are small, thin, disposable absorbent pads that can be used on their own on days of light flow. They can also be used in combination with a tampon, in case of leaks or discharge.

Reusable pads

These are usually made of cotton, bamboo, or other natural absorbent fibres, and are often available at health food stores. They can be washed with detergent and reused. Some have velcro tabs to secure them around your underwear.

What Do I Need To Know About Using A Pregnancy Due Date Calculator

A due date calculator may not be completely accurate. This is especially true if you arent exactly sure when you had your last period, you have irregular periods or you dont know when you conceived. You should see your provider for a more precise test, such as an ultrasound, to confirm your due date.

Who Is The Father Of My Baby

If you have been with more than one man during your cycle, you may be wondering: “Who is the father of my baby?”

You can use your dates to try to figure it out, of course, but your best chance at knowing without a doubt who the father is would be to have a paternity test done once the baby is born.

If you would like to try to figure it out and you have regular cycles, here’s how:

  • Using a calendar, mark your last period on the calendar and figure out your possible dates of ovulation . Mark your possible days of ovulation with an ‘O’.
  • Think of each time you were with someone. Using #1 and #2 , mark each encounter on your calendar.
  • Do any of the #s fall within your ovulation dates?
  • Once you have your calendar marked, it’s time to analyze. Start with the first man. Were you with him any time leading up to ovulation or during ovulation? If so, he could be the father. Same thing with the second man, and so on.

    How Is The Due Date Calculated

    How to count your menstrual cycle

    The expected date of delivery is calculated by adding one year, subtracting three months, and adding seven days to the first day of a woman’s last menstrual period . The result is approximately 280 days from the LMP.

    Example: LMP = 8 May 2019+ 1 year = 8 May 2020- 3 months = 8 February 2020+ 7 days = 15 February 2020

    The calculation method above does not always result in a 280 days because not all calendar months are the same length, not does it account for leap years. In modern practice, calculators, reference cards, or sliding wheel calculators are used to add 280 days to LMP.

    LMP may not be the best date to use as the basis of a due date calculation, but it remains popular because few women know exactly what day they ovulate or conceive a pregnancy, and because no algorithm can predict the exact day that spontaneous labour will occur no matter what considerations are taken into account.

    What If I Have Irregular Periods Or Long Cycles

    Some women have cycles that are consistently longer than the average 28-day cycle. In these cases, a pregnancy wheel can still be used, but some simple calculations are necessary.

    The second half of a womans menstrual cycle always lasts for 14 days. This is the time from ovulation to the next menstrual period. If your cycle is 35 days long, for example, then you probably ovulated on day 21.

    Once you have a general idea of when you ovulated, you can use an adjusted LMP to find your due date with a pregnancy wheel.

    For example, if your menstrual cycle is usually 35 days long and the first day of your LMP was November 1:

  • Add 21 days .
  • Subtract 14 days to find your adjusted LMP date .
  • After you calculate your adjusted LMP date, simply mark it on the pregnancy wheel and then look at the date where the line crosses. That is your estimated due date.

    Some pregnancy wheels may allow you to enter the date of conception which occurs within 72 hours of ovulation instead of the date of your LMP.

    How Does The Menstrual Cycle Work

    The menstrual cycle is controlled by a complex orchestra of hormones, produced by two structures in the brain, the pituitary gland and the hypothalamus along with the ovaries.

    Should I Watch For Any Problems

    Most girls don’t have any problems with their periods. But call your doctor if you:

    • are 15 and haven’t started your period
    • have had your period for more than 2 years and it still doesn’t come regularly
    • have bleeding between periods
    • have severe cramps that don’t get better with ibuprofen or naproxen
    • have very heavy bleeding
    • have periods that last more than about a week
    • have severe PMS that gets in the way of your everyday activities

    What If My Cycle Is Longer Or Shorter Than 28 Days

    A typical menstrual cycle is 28 days , with ovulation occurring halfway through the cycle. The second half of the menstrual cycle is fixed at approximately 14 days, so a woman can count back from her last period to see when she ovulated. So if your cycle is longer, e.g. 35 days, youll probably ovulate later too around day 21. If your cycle is shorter, e.g. 25 days, youll probably ovulate earlier around day 11.

    Pregnancy Following Assisted Reproduction Techniques

    Not infrequently, practitioners are called upon to manage pregnancies resulting from in vitro fertilization or intrauterine insemination. The GA of pregnancies resulting from in vitro fertilization can be precisely calculated from the time of embryo replacement however, conception may be delayed for a few days in pregnancies resulting from intrauterine insemination. In patients who have had ovulation induction, calculate GA from the day of human chorionic gonadotropin administration.

    Diagnosis And Tests For A Late Period And Pregnancy

    There are both at-home tests and blood tests available to determine if pregnancy has occurred. Both are considered safe methods of detecting pregnancy.

    • At-home tests: These test your urine for a pregnancy hormone called hCG. At-home tests are easy, quick, and convenient. However, they are not able to detect pregnancy as early as blood tests. They are most accurate if you wait one week after a missed period to use them.
    • Blood tests: Blood tests require a visit to your doctor. But they can detect pregnancy much earlier than at-home tests.

    What Is The Last Menstrual Period

    The LMP is the date of the first day of the last menstrual period you had before conceiving. It is the first day that your last menstrual cycle begins when you see bright red blood, not just a little brown spotting. You should keep track of your LMP each month, either with an online calculator or just by recording it on a calendar each month. That is the date you use when entering the LMP on an online period calculator.

    Whether you are trying to get pregnant or not trying to get pregnant, keeping track of your menstrual periods is vital. Besides pregnancy, missing a menstrual period could also be a sign of other issues like missed ovulation.

    What Is One Months Notice

    How Soon Can I Take a Pregnancy Test?

    The interpretation of a months notice in a termination clause and whether a qualifier, such as a calendar months notice, bears any significance, has been the subject of debate in our law for some time.

    The interpretation of a months notice in a termination clause and whether a qualifier, such as a calendar months notice, bears any significance, has been the subject of debate in our law for some time.

    In 2009, the court in SAMRO v Mphatsoe considered whether this phrase meant:

    1. Any 30-day period, with the result that notice may be given on any day of the month and the notice period will then terminate in 30 days time or 2. The beginning of any given month to the end of the same month, with the result that notice may be given on the first day of the month and will continue until the last day of the month. Accordingly, where notice is given on any day of the month, the notice period will only commence on the first day of the following month and will continue until the last day of that same month.

    Date Of Pregnancy Test

    Knowing the date of the first positive pregnancy test result allows the calculation of a minimum GA. This depends on the sensitivity of the test. For example, if the test was performed 4 weeks ago and the test is known to return positive results as early as 1 week after conception, then the minimum conceptional age would be 5 weeks . This information can be useful in clinical practice if the test finding has been documented by a health care professional.

    What Will My First Period Feel Like

    You may find your first period comes and goes with very little in the way of symptoms, or you may find you experience quite a bit of discomfort. Common symptoms include:

    • Cramping in the lower abdomen
    • Breast tenderness
    • Diarrhea or nausea
    • Dizziness

    Most of these symptoms do not last long, and can be treated with ibuprofen or other over-the-counter pain relief medications. A heating pad or hot water bottle on the abdomen or lower back can help ease pain in these areas. More details on menstrual pain and other symptoms can be found here .

    Ultrasonography In The First Trimester

    In the early first trimester, when no structures are visible within the gestational sac, GA may be estimated from the sac diameter. Several formulas can accomplish this. A common method is to measure the mean sac diameter , by calculating the mean of the 3 sac diameters. GA is then determined by consulting a table. An alternative simpler method is to add 30 to the sac size in millimeters, to give GA in days. By the time the embryo becomes visible on ultrasound the sac diameter is no longer accurate in estimating gestational age.

    If cardiac activity can be detected but the embryo is not measurable, the GA is about 5.5-6.0 weeks.

    GA in the first trimester is usually calculated from the fetal crown-rump length . This is the longest demonstrable length of the embryo or fetus, excluding the limbs and the yolk sac.

    When Do Most Girls Get Their Period

    Listening to “Red” (Taylor’s Version) FOR THE FIRST TIME! Full Album REACTION

    Most girls get their first period when they’re around 12. But getting it any time between age 10 and 15 is OK. Every girl’s body has its own schedule.

    There isn’t one right age for a girl to get her period. But there are some clues that it will start soon:

    • Most of the time, a girl gets her period about 2 years after her breasts start to develop.
    • Another sign is vaginal discharge fluid that a girl might see or feel on her underwear. This discharge usually begins about 6 months to a year before a girl gets her first period.

    General Overview Of The Menstrual Cycle:

    The menstrual cycle includes several phases. The exact timing of the phases of the cycle is a little bit different for every woman and can change over time.

    Cycle days

    The first day of menstrual bleeding is considered Day 1 of the cycle.

    Your period can last anywhere from 3 to 8 days, but 5 days is average.

    Bleeding is usually heaviest on the first 2 days.

    Days 6-14

    Once the bleeding stops, the uterine lining begins to prepare for the possibility of a pregnancy.

    The uterine lining becomes thicker and enriched in blood and nutrients.

    Day 14-25

    Somewhere around day 14, an egg is released from one of the ovaries and begins its journey down the fallopian tubes to the uterus.

    If sperm are present in the fallopian tube at this time, fertilization can occur.

    In this case the fertilized egg will travel to the uterus and attempt to implant in the uterine wall.

    Days 25-28

    If the egg was not fertilized or implantation does not occur, hormonal changes signal the uterus to prepare to shed its lining, and the egg breaks down and is shed along with lining.

    The cycle begins again on Day 1 menstrual bleeding.

    How Does It Work

    The conception calculator figures the gestational age of the baby to determine the date of conception. Since the exact date of conception is hardly ever known, the conception calculator can use the first day of the last menstrual period you have to determine the range of days in which conception would have occurred.

    You can also use the conception calculator if you know the due date of your baby. The baby can typically be dated 5 or 6 weeks after your last menstrual period to determine the gestational age of the baby and the approximate due date.

    If you know either of these figures, you can input this information into the conception calculator along with the current date to find out the possible days of conception.

    Again, the conception calculator bases this off of the average 28-day cycle. If you have a shorter or longer cycle you will have to account for that manually, moving the range over a few days in either direction so to speak.
