Ovulation Cycle: When Does Ovulation Occur
Outlined above is a fairly basic understanding of how ovulation works. In reality, ovulation and a womans monthly cycle are actually quite complex. While a monthly cycle is usually considered to be about 28 days, most women will find their cycles vary in length.
Some women even experience very irregular cycles. Conditions like PCOS might cause spotting or even bleeding more days than not. That means that, while the average or ideal cycle is the one most often described, any specific woman may find her schedule is somewhat different.
Ovulation occurs about halfway through a cycle, between days 10 and 22 of your cycle . The levels of estrogen and other hormones rise until the release of an egg is triggered. The egg moves from the ovary to travel down the fallopian tube.
After the egg is released, a womans body begins the luteal phase of their cycle. The egg moves into the fallopian tube and may be fertilized or may end up being expelled with the uterine lining.
Some forms of non-hormonal birth control, like the fertility awareness method, depend on tracking the progress of your cycle. The fact that cycles arent reliably regular means that they are less effective. A more reliable method may be to look for physical signs of ovulation.
What Is Toxic Shock Syndrome
Toxic shock syndrome is a rare but sometimes deadly condition caused by bacteria that make toxins or poisons. In 1980, 63 women died from TSS. A certain brand of super absorbency tampons was said to be the cause. These tampons were taken off the market.
Today, most cases of TSS are not caused by using tampons. But, you could be at risk for TSS if you use more absorbent tampons than you need for your bleeding or if you do not change your tampon often enough . Menstrual cups, cervical caps, sponges, or diaphragms may also increase your risk for TSS if they are left in place for too long . Remove sponges within 30 hours and cervical caps within 48 hours.9
If you have any symptoms of TSS, take out the tampon, menstrual cup, sponge, or diaphragm, and call 911 or go to the hospital right away.
Symptoms of TSS include:10
- Sudden high fever
How Long Is A Menstrual Cycle
For menstruating women, an average menstrual cycle lasts 28 days. It starts with the first day of the last period and ends with the first day of the next menstrual period. However, the length of women’s cycles varies, particularly for the first year or 2 after a young woman has her first period. Women may have cycles as short as 21 days, or as long as 45 days during the first few years. However, anything outside of this range may require medical attention.

Determining The Best Time To Have Sex To Conceive
Unfortunately, there’s no completely accurate method to detect that you are about to ovulate. It’s possible for an ovulation predictor kit, body temperature charts, and cervical mucus patterns to all indicate a slightly different ovulation day.
In a study of people with regular, 28-day cycles, ovulation occurred most commonly on day 15 after the start of the last menstrual period , followed by day 16 LMP and day 14 LMP . Researchers found a 10-day spread of observed ovulation days even among a group of people with “clockwork” cycles, and a similar variation for people whose cycles were a little longer or shorter.
Another group of researchers set out to pinpoint the most commonly fertile day in the menstrual cycle across the general populationincluding those with irregular cyclesusing menstrual period surveys and ultrasound measurements rather than ovulation signs. They found a sharp rise in the probability a person will conceive beginning at day 7 LMP, reaching a maximum probability of conception of 13% at day 15 LMP. By day 25 LMP, the statistical probability of conception is zero, according to the data.

What Is The Menstrual Cycle
The menstrual cycle is the monthly hormonal cycle a females body goes through to prepare for pregnancy. Your menstrual cycle is counted from the first day of your period up to the first day of your next period. Your hormone levels usually change throughout the menstrual cycle and can cause menstrual symptoms.
How Can You Know If You’re Not Ovulating
Some people do not ovulate regularly, or at all. One in 10 people with ovaries experience anovulation, or periods in which an egg is never released during their menstrual cycle, at some point during their childbearing years. If you’re not ovulating, no amount of sex will get you pregnant.
Irregular periods or completely absent periods are the number one sign that ovulation may not be occurring, or may be occurring infrequently. It is possible to have regular periods and not be ovulating, but this is uncommon.

Signs Of Ovulation To Look Out For
Here are the seven main ovulation symptoms lookout for:
- Your basal body temperature falls slightly, then rises again.
- Your cervical mucus becomes clearer and thinner with a more slippery consistency similar to that of egg whites.
- Your cervix softens and opens up.
- You may feel a slight twinge of pain or mild cramps in your lower abdomen.
- Your sex drive may increase.
- You may notice some light spotting.
- Your vulva or vagina may appear swollen.
How To Spot The Signs Of Ovulation
Ovulation usually happens about 10 to 16 days before the start of your next period, so it helps to know your cycle length before you start trying to conceive.
You may never have considered when you might ovulate within your cycle, and if you have been using a hormone contraceptive such as the Pill, you wont have had a natural menstrual cycle for a while.
As a first step, mark on your ovulation calendar the dates that you bleed during a period. You can then count how many days from the first day of your period to your next period to work out the length of your cycle.

Using Ovulation Test Kits
Ovulation predictor kits are available from chemists and are fairly simple to use. They work by detecting a hormone in your urine that increases when ovulation is about to take place.
The simplest ovulation test kits check for luteinising hormone , which surges 24-36 hours before ovulation. This will help to identify the best two days for conception, although a woman can be fertile for a day or so before and after this time.
It is best to become familiar with your usual menstrual cycle to help figure out when you should start testing. If you have an irregular cycle then an ovulation predictor kit can help you identify the time of ovulation, but expect to use more of the test strips.
When Do You Ovulate After Your Period
Normally, women ovulate about halfway through their menstrual cycle. The cycle begins on the first day of a period and ends the day the next period begins. To get a rough date of ovulation, figure out the next day you expect a period to begin. The day about halfway along is an estimate for your ovulation date.
An average cycle is about 28 days, though they can often vary. As a result, while its possible to make a guess at when your next period starts, its not considered a reliable guess.

How Does Ovulation Relate To Periods
Ovulation is the release of an egg from the ovaries. The same hormones that cause the uterus lining to build up also cause an egg to leave one of the ovaries. The egg travels through a thin tube called a fallopian tube to the uterus.
If the egg is fertilized by a sperm cell, it attaches to the wall of the uterus, where over time it develops into a baby. If the egg is not fertilized, the uterus lining breaks down and bleeds, causing a period.
How To Know If You Are Ovulating
Can you ovulate right after period? Yes, you can. But are there any signs or tests to say you are ovulating?
Signs of Ovulation
Common ovulation signs are as follows:
- Light spotting
- Change of the cervical fluid
- Change of the cervical firmness and position
- Abdominal pain which is dull, usually located on one side of the abdomen
- Abdominal bloating
- Elevated levels of luteinizing hormones
- Increased libido
- Constant changes of the basal body temperature chart
- Increased sense of smell, taste, and vision
Women will not notice all the above-mentioned signs of ovulation. In general, women will notice only a few signs of ovulation with each menstrual cycle.
Charting Your Basal Body Temperature
When trying to detect the exact time of ovulation, charting the basal body temperature can help. The body temperature should be measured every day using a thermometer and the findings are written on a chart every day.
The temperature should be measured immediately after you wake up, before even getting out of the bed. Wake up around the same time of the day every morning, so the readings of your basal body temperature can be measured at the same time.
If you notice that your basal body temperature has increased by 0.4 degrees Fahrenheit, you are probably ovulating. Maybe understanding how basal body temperature charting works is not easy during the first months. However, after a couple of months, you should be able to understand this charting of your basal body temperature and notice patterns.

Tips For Those Preventing Pregnancy
Have sex only on days that are considered safe. The safest time is six or more days before ovulation, where the chance that a woman will get pregnant is virtually zero. These are the days of your period and a few days after the period. So whilst you can technically pregnant three days after your period, it is less likely on this day of your cycle.
Especially if you are planning to have sex during your fertile period, always use protection. Contraceptives come in many forms and methods. Birth control pills aim to prevent unplanned pregnancy by releasing synthetic hormones that prevent ovulation. However, when dealing with contraceptives, it is important to find the one that is right for you, as not doing so can lead to hormonal imbalances and changes to your body or mood.
Tips For Those Trying To Conceive
Most of the time, it’s all about finding the perfect timing. It is important to engage in sexual intercourse right away when you confirm that you are indeed fertile or are currently on your fertile window .
If you do fall pregnant, implantation bleeding can occur 10 to 14 days after conception. This is completely normal and can be a sign of a fertilized egg attaching to the uterus lining.
The best way to know your chances of pregnancy is to know your own body, be aware of its cycles and make sure you are always in optimal health.

How Long After Ovulation Does A Woman Get Her Period
On average, a woman will start her period 14 days after ovulation. However, every womans cycle is different, and this should only be used as a guide.
Menstruation is the bodys way of shedding the uterine lining. Each woman has a unique cycle, although the average cycle is 28 days long. The average period lasts from three to five days.
It is easy for most women to track ovulation with a little practice. A combination of period tracking, taking her temperature and studying cervical fluids can help a woman figure out when she is ovulating, according to the American Pregnancy Association. Generally, a woman ovulates 11 to 21 days after the end of her last period or from 12 to 16 days before she expects her next period to begin.
During ovulation, an egg is only available for fertilization for 12 to 24 hours. However, since sperm can live in the body for up to five days, it is possible to get pregnant right after ovulation. A missed period may signal a pregnancy.
A period is the shedding of the uterine lining that builds up to accommodate a fertilized egg. if no pregnancy occurs that month, the body rids itself of the additional lining and the unfertilized egg.

When To See A Doctor
Women who track their fertile window with the aim of getting pregnant should see their doctor for preconception planning.
As well as identifying barriers to conceiving, a doctor can advise on the use of folic acid or prenatal supplements to encourage a healthy pregnancy.
Most couples who engage in frequent, unprotected sex will conceive within 12 months.
Women under 35 years of age should see their doctor if they do not conceive after a year of trying. Those over 35 years of age should seek medical advice after 6 months of trying to conceive.
Anyone who has irregular cycles or does not appear to ovulate should also speak to their doctor. There may be an underlying medical cause that is preventing ovulation and conception.
Ovulation predictor kits and fertility monitors are available for purchase online.
What About Right Before Your Period
The likelihood of getting pregnant right before your period is extremely low. For women with a typical 28- to 30-day cycle or longer and their cycles are regular, it is fairly safe to say your ovulation occurred between Day 11 and Day 21. The egg is only available for 12 to 24 hours for conception.
This means the days right before your period are the safest to have sex without the expectation of getting pregnant. The number of safe days right before your period go up with longer cycles and lessen with shorter cycles.
If you wait 36 to 48 hours after ovulation, you should be beyond the possibilities of conception. The further you are from ovulation, the less likely your chance for conceiving. This is not the time to have sex if you are trying to conceive. Its still a good time to enjoy intimacy with your partner.
