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

I thing is for sure: Conception can merely occur around the time your are ovulating, about midway through your bike. Ovulation lasts 12 to 48 hours, and eggs released from your ovaries during that fourth dimension live for about a day. Sperm, meanwhile, tin survive in your reproductive tract for around 72 hours. That ways that having sexual practice anywhere from most four days earlier you ovulate to about ane 24-hour interval after could result in pregnancy. That 6-day flow during each menstrual cycle is known as your fertile window.

Unfortunately, the timing of that fertile window can differ from person to person and even month to month. For that reason, while there are times of the month that make yous more probable to conceive, there is a small adventure you can get pregnant closer to your period than you lot think.

Immediately Before Your Period

By and large, your likelihood of conceiving right before your flow is low. Ovulation normally occurs several days before that: almost midway between the offset twenty-four hour period of your terminal menstrual period (day i LMP) and the start of your next menstruation.

A "regular" cycle is 28 days long, only many people have slightly shorter or longer cycles. In one report of 32,595 people, people with cocky-reported regular periods had menstrual cycles ranging from 23 to 35 days long. The virtually mutual twenty-four hour period to ovulate is day 15 LMP.

If you are trying to be mindful of your cycles as a natural form of birth control, be aware there's a slight chance of pregnancy if you ovulate later in the cycle or simply miscalculate the dates of your next menses. In one big study, even people who reported having regular menstrual cycles had a half-dozen% chance of being in their fertile window on the day they expected their next flow to begin.

If you are trying to conceive, now would not be the best time to start. You can still savor sex but are more than probable to get significant if you try again later on your period.

During Your Period

The chances are pretty skilful that you volition not get pregnant if you accept sex during your menstruation. Flow is the signal that the ovum was non fertilized or implanted, leading to a driblet in hormone levels and the shedding of the uterine lining. During this stage in your cycle, your gamble of pregnancy will remain negligible.

However, the odds of conception during your catamenia isn't naught for everyone, every calendar month. If you have a very short cycle, ovulation may occur soon later your menses. Given that sperm tin can live inside you for upwards to three days, having sex at the stop of your period may lead to fertilization in the days following information technology. Ane study charting the nigh mutual conception days in the menstrual cycle shows that odds beginning to rise on twenty-four hours 7 LMP—only a week past your first day of bleeding.

It'southward too important to note that what you may think is a menstruation might not be. An estimated ii.8% of people with periods have spotting effectually ovulation, which is actually when you are nigh fertile. In other cases, spotting may be implantation haemorrhage, a very early on sign of pregnancy. Unlike a regular period, spotting in these circumstances is typically lighter in color and catamenia.

Following Your Catamenia

While you lot may assume that your odds of getting pregnant are slim in the first few days post-obit your period, you lot are actually moving into a new fertility window. Researchers have shown that a person's chances of formulation jumps starting 7 days after the first of your last menses and rises steadily after that, peaking effectually day 15 LMP.

Your run a risk of getting pregnant in the days just post-obit your period rises when you have a shorter length betwixt periods, considering that usually means y'all ovulate shortly subsequently your period ends. Research has shown that people with a 23-24-hour interval menstrual bicycle, for instance, have a 9% hazard of ovulating on day 10 LMP. That means they are fertile—able to get pregnant—between 6 and 11 days afterwards the starting time of their last catamenia.

Remember, even when you are in between periods and in your suspected fertile window, that does not hateful you volition 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 foreclose conception and fertilization. If you are timing sex activity to get pregnant and having problem after several months, consider talking to a fertility medico about tests y'all can take to better understand how to maximize your chances of conceiving.

A Word From Verywell

Your chance of conceiving inches upward in the days following the end of your period. Doctors typically recommend that couples who are trying to have a baby have sex between days 7 and 20 of your menstrual cycle (counting from the showtime day of your terminal flow).

On the other hand, if you don't want to get pregnant, you should avoid sexual activity during that window, or better still, utilise at least 1 method of birth control every fourth dimension yous have intercourse. This non but includes the days leading upwardly to ovulation but on "safe" days during and around your period when the adventure, however slight, nevertheless exists.

Whether getting pregnant is a goal or something to avert, it's ever a skilful thought to talk to your doctor. They can assistance you improve sympathize your body and your cycles, making sex activity more fun and less stressful no matter what stage of life you lot are in.
