Calculate When Ovulation Starts
If you have a 30-day cycle, then ovulation will occur approximately on day 16 of your cycle. Ovulation occurs 10-14 days before your next period, so you will get an approximate ovulation date by subtracting 14 from the number of days in your cycle . This means that ovulation will occur 16 days after your period starts. If you have your period on January 1, ovulation will take place on January 17.
Use the chart below to determine when you’re most likely to ovulate based on the length of your menstrual cycle. Find the length of your cycle in the left-hand column to see how many days after the beginning of your period you will ovulate and when you’re at your most fertile.
From The Menstrual Period To Ovulation
When your menstrual cycle begins, your estrogen levels are low. Your hypothalamus sends out a message to your pituitary gland which then sends out the follicle stimulating hormone . This FSH triggers a few of your follicles to develop into mature eggs. One of these will develop into the dominant follicle, which will release a mature egg and the others will disintegrate.
As the follicles mature they send out another hormone, estrogen. The high levels of estrogen will tell the hypothalamus and pituitary gland that there is a mature egg. A luteinizing hormone is then released, referred to as your LH surge. The LH surge causes the egg to burst through the ovary wall within 24-36 hours and begin its journey down the fallopian tube for fertilization.Ovulation Predictor Kits work by detecting this LH surge. The follicle from which the egg was released is called the corpus luteum, and it will release progesterone that helps thicken and prepare the uterine lining for implantation. The corpus luteum will produce progesterone for about 12-16 days
If an egg is fertilized, thecorpus luteum will continue to produce progesterone for a developing pregnancy until the placenta takes over. You can begin looking for pregnancy symptoms as early as a week after fertilization. You can also begin testing for pregnancy as early as 7-10 days past your ovulation date with an Early Detection Pregnancy Test.

What Does It Mean When You Bleed During Ovulation
Ovulation bleeding happens shortly after ovulation in the middle of your cycle, about 10 16 days after your period. Its due to a rapid surge of the hormone estrogen at ovulation, followed by a swift plunge in estrogen.
That said, other factors besides a dip in estrogen may cause mid-cycle bleeding, which well get to.

When Do Most Girls Get Their Period
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.
Is Ovulation The Only Time You Can Become Pregnant
No. While the egg can only be fertilized in the 12 to 24 hours after its released, sperm can live in the reproductive tract under ideal conditions up to 5 days. So, if you have sex in the days leading up to ovulation or on the day of ovulation itself, you may become pregnant.
six daysTrusted Source leading up to and including ovulation make up whats called the fertile window. Again, this is the period of time when sexual intercourse may lead to pregnancy.
The sperm may wait around for several days in the fallopian tubes after sex, ready to fertilize the egg once its finally released. Once the egg is in the fallopian tubes, it lives for around 24 hours before it can no longer be fertilized, thus ending the fertile window.

Your Menstrual Cycle And Ovulation
Your menstrual cycle lasts from the first day of your period until the day before your next period starts. This is 28 days on average but longer or shorter cycles, from 21 to 40 days, are normal.
During your cycle, an egg is released from one of your ovaries and travels down the fallopian tube. It is usually released 10-16 days before your next period. Occasionally, a second egg is released, within 24 hours of the first egg.
The egg only lives for a maximum of 24 hours after ovulation, and a sperm must meet the egg within that period for pregnancy to happen.
You can get pregnant up to 2 days after you ovulate. But if you’ve had sex in the 7 days before ovulation, it’s possible to get pregnant because sperm can live inside a woman’s body for up to 7 days and fertilise the egg when it’s released.
The length of a menstrual cycle can vary over time, so to make sure your calculations are as precise as possible, measure your menstrual cycle over the course of 12 months.

What Happens After Conception Occurs
Once conception has occurred, the fertilized egg will travel to the uterus. As the egg is moving, the cells will continue to divide and grow in size. When the egg arrives at the uterus, it will attach to the uterine wall . It starts to produce the hormone that pregnancy tests detect, hCG, after implanting.
How To Track Your Ovulation Cycle:
A womans monthly cycle is measured from the first day of her menstrual period until the first day of her next period. On average, a womans cycle normally is between 28-32 days, but some women may have much shorter or much longer cycles. Ovulation can be calculated by starting with the first day of the last menstrual period or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 Day 21 of their cycle, counting from the first day of the LMP. This is what many refer to as the fertile time of a womans cycle because sexual intercourse during this time increases the chance of pregnancy. Ovulation can occur at various times during a cycle and may occur on a different day each month. It is important to track your cycle and fortunately, there are a number of free fertility charting tools available to help women identify their peak fertile days.

How To Know When Youre Ovulating
Knowing when you ovulate can help you plan for sex at the right time and improve your chance of getting pregnant. You can keep track of your menstrual cycles on a chart, in a diary, or on a free period-tracker app on your smartphone.
To work out the length of your menstrual cycle, record the first day you start bleeding . This is day 1. The last day of your cycle is the day before your next period begins.
-
Some people think the menstrual cycle and a period are the same thing.
A period is when you bleed .
A menstrual cycle starts on the day when a period starts and ends the day before the next period. A cycles length is considered normal if its between 21 and 35 days. They can vary between women and from one cycle to the next.
- Working out your average menstrual cycle length
If your menstrual cycles are different lengths you can work out your average cycle length.
The number of days in a womans menstrual cycle can vary month to month. Periods are not always regular. It can be useful to work out an average cycle length, based on the length of three menstrual cycles, to estimate when youre most likely to be ovulating.
If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.
Example
Sarah tracked her last three menstrual cycles by counting the time from the first day of one period, to the day before the next period.
Cycle 1 was 28 days Cycle 2 was 32 days Cycle 3 was 27 days
28 + 32 + 27 = 87
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.

Your Ovulation Timing Depends On The Length Of Your Cycle
Ovulation is when one of your ovaries releases an egg.
You only ovulate once per cycle. You may release more than one egg at a time . But youll never ovulate, then ovulate again without having a period in between.
Ovulation occurs near the middle of your cycleafter your follicular phase, and before your luteal phase. The events play out like this:
Your cycle starts with your period.
Day 1 is considered the first day of steady bleeding . Periods last 5 days on average, but anywhere between 2 and 7 days is normal.
Your follicular phase varies in length.
It starts when your period starts , and ends with ovulation. The length of your follicular phase depends on how quickly youre able to make enough of the hormones that activate your folliclessacs in the ovaries that each contain an egg. Once activated, one dominant sac will rupture and release its egg.
Ovulation takes about 1 day.
The release of an egg triggers the production of hormones that prepare the body for a potential pregnancy.
Those pregnancy hormones rise and fall during your luteal phase.
They rise during the first half of the luteal phase, and you may feel a natural high and more energy as a result. Then they fall during the second half, and you may experience PMS symptoms.
If no egg was fertilized that cycle, pregnancy hormones are no longer needed. Their levels will continue to fall, which will trigger a period, and the cycle starts over again.
Menstrual Cycle And Ovulation
At birth, a female fetus has 1 to 2 million immature eggs called oocytes inside her ovaries, which is all the eggs she will ever produce, according to the Cleveland Clinic. By the time a girl enters puberty, about 300,000 of these eggs remain. Approximately 300 to 400 of the remaining eggs will be ovulated during a woman’s reproductive lifetime, the Cleveland Clinic says.
A likely sign that a woman is ovulating is that she is having regular, predictable periods that occur every 24 to 32 days, according to the Centers for Disease Control and Prevention .
With every monthly menstrual cycle, a woman’s body prepares for a potential pregnancy. The cycle is regulated by hormones, including the sex hormones estrogen and progesterone, as well as follicle-stimulating hormone and luteinizing hormone. Hormones play a key role in all stages of the menstrual cycle, allowing the ovum to mature and eventually be released.
When a mature egg leaves a woman’s ovary and travels into the fallopian tube, a sperm cell can fertilize the egg. Sperm can live inside a woman’s reproductive tract for about 3 to 5 days after sexual intercourse, according to the Mayo Clinic. For pregnancy to take place, a sperm cell must fertilize the egg within 12 to 24 hours of ovulating, according to the Mayo Clinic. The fertilized egg then travels to the uterus, or womb, where it can attach to the lining of uterus and develop into a fetus.

Discharge Changes When You Ovulate
The changes in your discharge over the course of your menstrual cycle also hold clues about when you might be ovulating.
If your cervical mucus is…
- Dry or sticky: Its unlikely youre ovulating
- Creamy: Ovulation may be coming
- Wet or watery: Ovulation may start soon
- Wet and stretchy : You may be at your day of ovulation
Its worth noting that cervical mucus is just one component of vaginal discharge, which can also include vaginal lubrication, arousal fluid and more.
Again, making such observations is not an exact science and no womans body is a clock. But if you keep a period diary and ovulation calendar, it might be worthwhile to also note any observable changes to cervical mucus. Over time, you may see a pattern emerge.
Ovulation: How Many Days After A Period Is It
If your cycle is always exactly 28 days long, ovulation occurs about 14 days after the first day of your period. But according to the research, if your cycle is always exactly 28 days long, youre practically a unicorn.
One study measured the cycle lengths of women who identified as having regular menstrual cycles, and found 46% of them actually had cycles that varied within a 7 day range. An additional 20% had cycles that varied within a 14 day range . Couple that with the ~18% of women who identify as having irregular menstrual cycles , and its safe to say that most peoples cycles are not always exactly 28 days long.
Although cycles lasting anywhere between 21 and 45 days are considered normal , you cant accurately predict your ovulation timing by simply counting 14 days after your period starts if you deviate from the average 28 day cycle.
More detective work is needed, and this article is your guide. It covers:
- Why ovulation timing depends on the length of your cycle
- How to know when ovulation occurs if your cycles are longer or shorter than 28 days
- Why ovulation isnt just a fertility concernits a big deal for your period, too!
