Whether y'all are trying to conceive or looking to avert pregnancy without birth command, the timing of intercourse is important. Chances are lower that you can get meaning from having sex immediately earlier or during your menstruation, for case. Only because many people accept irregular menstrual cycles, perfect timing—to get pregnant or ensure you don't—can be tricky.

One thing is for sure: Conception tin only occur effectually the time your are ovulating, about midway through your cycle. Ovulation lasts 12 to 48 hours, and eggs released from your ovaries during that time live for near a solar day. Sperm, meanwhile, can survive in your reproductive tract for effectually 72 hours. That means that having sex anywhere from well-nigh four days before y'all ovulate to about ane day subsequently could result in pregnancy. That half-dozen-day period during each menstrual bike is known as your fertile window.

Unfortunately, the timing of that fertile window tin differ from person to person and even month to calendar month. For that reason, while there are times of the calendar month that make y'all more likely to conceive, there is a small hazard you tin go pregnant closer to your period than you lot think.

Immediately Before Your Period

By and large, your likelihood of conceiving correct earlier your period is low. Ovulation commonly occurs several days earlier that: about midway between the showtime twenty-four hours of your last menstrual period (twenty-four hours i LMP) and the kickoff of your next menses.

A "regular" cycle is 28 days long, but many people take slightly shorter or longer cycles. In i report of 32,595 people, people with cocky-reported regular periods had menstrual cycles ranging from 23 to 35 days long. The near common day to ovulate is twenty-four hours 15 LMP.

If you are trying to be mindful of your cycles equally a natural course of birth control, be aware at that place's a slight chance of pregnancy if yous ovulate later on in the cycle or simply miscalculate the dates of your next catamenia. In one big study, even people who reported having regular menstrual cycles had a six% take chances of being in their fertile window on the day they expected their next period to begin.

If y'all are trying to conceive, now would not be the best time to beginning. You tin notwithstanding enjoy sexual practice but are more than likely to get meaning if yous attempt again subsequently your menses.

During Your Menstruum

The chances are pretty good that y'all will not become pregnant if yous have sex during your period. Flow is the point that the ovum was not fertilized or implanted, leading to a drop in hormone levels and the shedding of the uterine lining. During this stage in your bicycle, your risk of pregnancy will remain negligible.

Nonetheless, the odds of formulation during your period isn't zilch for everyone, every month. If you lot have a very brusque cycle, ovulation may occur soon after your menstruum. Given that sperm can live inside y'all for upwards to three days, having sex at the terminate of your period may atomic number 82 to fertilization in the days post-obit it. One report charting the most common formulation days in the menstrual wheel shows that odds start to ascent on twenty-four hours vii LMP—just a week past your first day of haemorrhage.

It'due south besides important to annotation that what you may remember is a menses might not exist. An estimated 2.eight% of people with periods take spotting around ovulation, which is actually when yous are nigh fertile. In other cases, spotting may be implantation haemorrhage, a very early sign of pregnancy. Different a regular period, spotting in these circumstances is typically lighter in color and flow.

Following Your Period

While y'all may assume that your odds of getting pregnant are slim in the starting time few days post-obit your period, y'all are actually moving into a new fertility window. Researchers have shown that a person's chances of conception jumps starting seven days after the showtime of your last period and rises steadily afterwards that, peaking around day 15 LMP.

Your take chances of getting pregnant in the days only following your period rises when you have a shorter length between periods, because that usually means you lot ovulate presently after your period ends. Enquiry has shown that people with a 23-day menstrual bike, for example, have a ix% run a risk of ovulating on day x LMP. That means they are fertile—able to get pregnant—between 6 and 11 days after the start of their last period.

Remember, even when you are in betwixt periods and in your suspected fertile window, that does non mean you lot will necessarily get pregnant from sex. Structural problems with your uterus or fallopian tubes or issues with either your eggs or your partner's sperm can prevent conception and fertilization. If you are timing sex to get pregnant and having trouble afterward several months, consider talking to a fertility doctor about tests yous can take to ameliorate understand how to maximize your chances of conceiving.

A Discussion From Verywell

Your hazard of conceiving inches upward in the days post-obit the terminate of your menstruation. Doctors typically recommend that couples who are trying to accept a baby have sex between days 7 and twenty of your menstrual cycle (counting from the first mean solar day of your last period).

On the other hand, if you don't want to get pregnant, y'all should avert sexual activity during that window, or better yet, use at least 1 method of birth command every fourth dimension you take intercourse. This non simply includes the days leading upwardly to ovulation but on "safety" days during and around your period when the risk, nonetheless slight, nevertheless exists.
