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 first day of your period. This is day 1. The last day of your cycle is the day before your next period begins. A menstrual cycle starts on the day when a period starts day 1 and ends the day before the next period.
They can vary between women and from one cycle to the next. Periods are not always regular. If you add the number of days in three cycles and divide the total number by three, it gives you your average cycle length.
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. Your most fertile days are the three days leading up to and including the day of ovulation. Some women have very irregular cycles or find it difficult to work out an average cycle length. This can make it hard to work out when ovulation happens. Eggs and sperm need to come together at the right time for fertilisation to happen to create an embryo.
If you're trying to get pregnant, timing is everything. Dr Karin Hammarberg explains how to work out when you are ovulating and the right time to have sex to improve your chance of pregnancy. If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero. If she has sex on the day of ovulation, or the two days before, the chance of getting pregnant is around 30 percent. Professor Sarah Robertson, Director of Robinson Research Institute, University of Adelaide, highlights the key time before pregnancy that your health is most important to ensure your child has the best start to life.
Kerry Hampton, a registered nurse and fertility specialist, discusses the importance of fertility awareness, and how to determine your fertile window to improve your chances of conceiving.

After release, the egg moves to the fallopian tube, where it stays for 24 hours or so. Pregnancy occurs if sperm travels to the fallopian tube and fertilizes the egg during this time. If sperm does not fertilize the egg, the egg moves to the uterus and breaks down, ready to leave the body during the next menstrual period. According to the American College of Obstetricians and Gynecologists, ovulation takes place around 14 days before a person expects to have their next period if their monthly cycle is 28 days.
Most people ovulate between days 11 and 21 of their cycle. The first day of their last menstrual period LMP is day 1 of the cycle. Ovulation does not always occur on the same day every month and can vary by a day or more either side of the expected date. For example, if a woman ovulates on day 14, they can conceive on that day or within the following 24 hours.
However, their fertile window began a few days before ovulation because sperm can survive for up to 5 days inside the female body. So, even if a woman does not have sex on day 14 or 15, it is still possible to become pregnant if they had unprotected sex on days 9 to A study published in the journal Human Reproduction looked at data from 5, pregnant women.
The researchers found that the probability of a person getting pregnant rises sharply 7 days after the LMP. This probability of pregnancy is highest at 15 days and returns to zero by 25 days. The research also reports that older women and women with regular cycles tend to conceive earlier in their cycle. It is essential to note that these findings should only act as a guideline. Every person and every cycle is different. It can be helpful for a person to chart their monthly cycle and take note of the signs of ovulation to help pinpoint the exact day of ovulation each month.
Tracking the signs of ovulation can help someone determine the precise day they ovulate each month. Some of these signs, such as basal body temperature, will continue to change after ovulation has occurred.
For this reason, a person should not use temperature to predict the fertile window. Here's why: Around day seven of your cycle, you'll notice a vaginal discharge that seems a little springy to the touch.
Within a few days, it will turn white and creamy, a cue that your fertility is returning once again. It doesn't mean the egg has been released yet, but it indicates that ovulation is on the way and that your cervical mucus is a friendly environment for sperm. Remember, you can get pregnant right after your period, even if you're not yet ovulating. That's because sperm can live up to five days if it's trapped in fertile cervical mucus —so it behooves you to get a few of his swimmers in place.
Bayer, M. Your chances of conceiving: Good. An egg isn't technically released during this phase, but you'll want to step up your sexual routine in the event that you ovulate earlier than planned. Welcome to prime time for conception! No matter the length of menstruation, ovulation generally starts about 14 days before your next scheduled period. When it happens, your body temperature rises about a half a degree detected by a basal body thermometer —but bear in mind that this also takes place after you're already ovulating, which could be too late for conception.
Bayer explains. These kits detect a surge in luteinizing hormone LH that happens about 36 hours before you ovulate.
After the test kit shows this surge, Dr. Bayer recommends having sex in the next 24 to 36 hours. Sperm can survive for some time in the reproductive tract, so it will be ready to meet the egg once it's released during ovulation.
Another good indication of fertility is a change in the consistency of your cervical mucus. Bayer says. Test yours by sticking your index finger and thumb in your vagina to get a sample, then tapping your finger and thumb together.
If the consistency is thin and spreads easily between two fingers, you're good to go. Let's illustrate this data a bit: Let's say you have couples trying to get pregnant. This study shows that 81 get pregnant within six months. If you've recently stopped using a non-barrier-based method of birth control i. A team of researchers recently did a systematic review of the existing work on how different methods of birth control impacted the likelihood of getting pregnant within 12 months of TTC.
Here's what they found:. Time to pregnancy is also likely not affected by the duration of oral contraceptive use. The main takeaway here? There's no delay in the resumption of fertility for women coming off of the most popular methods of birth control, but women coming off of the implant and injection-based methods may see a slight delay. Chances are, if you're currently using birth control, you're not TTC — but how successful your birth control method is at preventing pregnancy differs significantly based on what you're using.
According to the Centers for Disease Control and Prevention CDC , the least effective birth control method is spermicide — of couples who only use this method over the course of a year, 28 out of will experience an unintended pregnancy within the first year of typical use.
This number falls to 18 out of over the course of a year for condoms, and further drops to 9 out of for the pill, the patch, and the ring. While a 9 in failure rate seems high for these hormone-based methods, it's important to remember that this rate takes into account user error. Because women don't always take the pill as directed or replace their patches and rings on schedule, failure rates for these methods are higher than they would be with perfect use.
There are some birth control methods that require less action on the part of women; for example, once you get an IUD, there's nothing you have to do to make sure it's doing its thang, except for remembering to get it replaced every years depending on the type you get. If you've read some of our previous blog posts on aging and fertility or have used our Timeline Tool , you likely know that fertility decreases as people with ovaries and those with sperm!
These changes in fertility are a function of both how many eggs we have left and how healthy those eggs are. Together, the changes in egg quality and quantity make it trickier to conceive as age goes up. There is some data from large-scale studies investigating the effect of age on cycle-based conception rates:. Your chances of conceiving on each day of your fertile window change as you age, and this may in part explain why time to pregnancy is longer among older people.
Different medical conditions may or may not! PCOS affects 1 in 10 people with ovaries, and is one of the leading culprits of infertility among couples seeking treatment at fertility clinics. In people with PCOS, ovulation is irregular and occurs less frequently. This means that people with PCOS ovulate infrequently if at all , and ovulation doesn't always occur at predictable intervals.
There are science-backed, FDA-approved options for people with PCOS to boost their chances of conception that work by improving the frequency and regularity of ovulation.
Clomid administration increases the chances of ovulation in people with PCOS, and metformin may, too.
