How to Calculate Difference Between Two Time Periods in C++

You can also use this period calculator to find out what is your fertility window – that is, the time when you’re most likely to get pregnant.

As sperm can live up to seven days inside your body, you can safely assume that the fertility window starts seven days before ovulation. It ends only one day after the ovulation, though, as the egg lives for maximum 24 hours.

Ovulation is the time when an egg is released from your ovaries. This is the time when you are most fertile. It usually happens about two weeks before the start of the next period. If you want to have a more precise estimate, you should monitor your body temperature and the changes in cervical mucus.

We try our best to make our Omni Calculators as precise and reliable as possible. However, this tool can never replace a professional doctor’s assessment. If any health condition bothers you, consult a physician.

When Does Conception Take Place

Conception starts at the moment of fertilisation, when the sperm penetrates the outer shell of the egg, and an embryo is formed. Over the next four to six days the embryo moves down the fallopian tube to the uterus, where it implants in the uterus lining and hopefully continues to grow. To check if you are pregnant, you should wait two weeks after ovulation before undertaking a pregnancy test.

How Long Should My Period Last

Periods can last anywhere between 3 and 8 days, but they usually last for 5 days. Bleeding tends to be heaviest during the first 2 days, and the blood tends to be typically red. On lighter days, blood may be pink, brown or black. Brown or black periods are due to the iron in your bloody reacting more with the air, due to the slower flow.

  • Birth control patch: This is a sticker that you place on your skin and replace each week. It contains both estrogen and progestin.
  • Vaginal ring: You place this ring-shaped device in your vagina and change it once a month. It contains both estrogen and progestin.
  • Injectable contraceptive: This is a progestin-only shot that your doctor gives you every three months.
  • Hormonal implant: This implant is a tiny rod-shaped device that a doctor places under the skin in your upper arm. It is effective for up to three years.

How Long Is My Fertility Window

The fertility window has a length of 8 days. The fertility window begins when sperm can theoretically survive within your body long enough to fertilise an egg. The fertility window ends with the maximum lifespan of an egg. As an egg can only survive 1 day outside of the ovaries, the window ends 1 day after ovulation.

What Is Menstrual Period

    Q What To Expect From Momjunctions Period Calendar

    MomJunctions period calendar requires you to input the date of your last menstrual period date to calculate your monthly period. The date here refers to the starting date of the last period cycle, not the ending one.

    The second input requires you to give the average length of time between your periods. Since the term varies from person to person, its not wise to assume the figure. You must be as accurate as possible to determine your most fertile days if you are planning to conceive.

    Once youve shared the inputs, the period calculator will show you the result. It wont just give you a heads up on your next period start date for the next 12 cycles, but will tell you about your most fertile days and if you are late for your period cycle. Even if your period is delayed, you will know the next expected date of your period. This way, you can keep a track of the length of your menstrual cycle and the number of days it lasted.

    Disclaimer:The period calculator provides the approximate dates by considering your regular menstrual cycle. If your menstrual cycles are irregular, the tool may have trouble pinpointing your day of ovulation or period. While period calculators are not 100% accurate, the menstrual cycle is still a very useful tool. MomJunction is not responsible for any associated deviations, failures or liabilities.

    If You Have A Longer Cycle

    Menstrual cycles are considered longer than normal if you go more than 35 days between periods. Called oligomenorrhea, it can have a number of different causes:

    • Your age. Cycles tend to be a little longer in the first few years after getting your period.
    • Your weight. Having too little body fat can cause your periods to slow or even stop. That can happen as the result of an eating disorder or extreme exercise or athletic training. Being obese can have an impact too.
    • Certain ovarian conditions.Polycystic ovarian syndrome and ovarian insufficiency syndrome can both slow or stop your periods.
    • Thyroid problems. Specifically, an underactive thyroid can slow the production of hormones that trigger ovulation.
    • Mental health issues. Both depression and high rates of perceived stress are associated with irregular cycles. Its allll connected, people.
    • Pituitary tumors. Your pituitary gland is responsible for making the hormones that control your menstrual cycle. But pituitary gland tumors can throw that system out of whack.
    • Menopause, early or right on time. The transition to menopause involves some wild hormone swings, which means your bleeding can become irregular or even disappear altogether for a month or 2.

    Longer-than average cycles arent automatically problematic , but they can often be a sign of an underlying issue. People who have fewer periods have a higher risk of developing endometrial cancer.

    Several factors influence the date and flow of period. They include:

    1. Diet And Exercise: Exercise and diet can affect your period and your chances of pregnancy. If you are training for an athletic event and are not eating properly, your estrogen levels can drop, halting your period.

    2. Weight: Being too thin can also delay your periods, making your body think that you are not healthy enough for bearing a child. If you are overweight, excessive estrogen could build in your body, causing heavy or irregular periods.

    3. Stress And Lifestyle: Stress can mess badly with your cycle. Lifestyle habits like drinking and smoking can cause irregular periods.
