The only 100% certain way to avoid pregnancy is to not have penis-in-vagina sex, or do any sexual stuff where sperm can get on a vulva or in a vagina (this is called abstinence).
There's only one way to find out for sure if you're pregnant: take a pregnancy test.
Generally, a woman who's trying to get pregnant has between a 15% and 25% chance of doing so each month. Despite those odds, most couples conceive within the first year of trying.
The most straightforward way is to wash the vaginal area gently with warm water. The American Sexual Health Association (ASHA) recommend using mild, unscented soap around the vaginal area. It is best to avoid perfumed soaps as these can cause irritation by disturbing the pH level of the vagina.
The pull-out method is about 80% effective. About one in five people who rely on the pull-out method for birth control become pregnant.
Most couples will get pregnant within a year if they have regular sex and don't use contraception. But women become less fertile as they get older. The effect of age on men's fertility is less clear.
Short answer: Yes! Even if sperm and semen come out of the vagina, you may still find yourself pregnant. This is regardless of whether you go or don't go to the bathroom right after sex. The fact is, there's hope that semen leaking out after sex does not hurt your chances of conceiving.
How many sperm do you need to get pregnant? It takes just one sperm to fertilize a woman's egg. Keep in mind, though, for each sperm that reaches the egg, there are millions that don't. On average, each time men ejaculate they release nearly 100 million sperm.
Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive — up to five days. Sperm can also be preserved for decades when semen is frozen.
The days before and during menstruation are the least fertile days of the menstrual cycle. People with a menstrual cycle that is shorter than 28 days could ovulate within days of their period ending. Menstrual cycles may shorten with age, particularly after the age of 35 years .
There's no way to know when there is or isn't sperm in pre-cum — that's one reason why the withdrawal method (pulling out) isn't the best at preventing pregnancy, even if they pull out before they ejaculate (cum). If you want to prevent pregnancy, put on a condom before your penis and vagina touch.
"Normal semen fluid from ejaculation contains greater than 40 million motile sperms compared to pre-ejaculate fluid, which has anywhere from no sperm to less than 5 million swimmers," says Dr. Hsieh.
Pregnancy can happen if any semen gets in your vagina or on your vulva. So the best way to make the pull out method effective is to use it with another type of birth control (like the ring, pill, or condoms). This way, if there's a slip up, you're still protected. Accidents happen.

You can't always tell when pre-ejaculate (AKA pre-cum) comes out of your penis. You may be able to feel a little wetness on the tip of your penis when it comes out, but you may not notice if you're having sex and other things around your penis are wet, too.
Ovulation usually occurs about 14 days before the start of a woman's period — the beginning of her menstrual cycle. She is less likely to become pregnant from unprotected intercourse in the day or two following ovulation, but it's still possible.
You won't run out of sperm cells, no matter how often you ejaculate. A number of studies have looked at semen samples from men who ejaculated several times a day. They found that while the sperm count lowered with each successive sample, it didn't fall beneath what experts consider to be a healthy sperm count.
How much sperm does it take? In theory, a single sperm is all it takes to get pregnant. But even in a large amount of semen — such as the quantity in one ejaculation — only a fraction of the sperm are healthy, moving, and sufficiently well-formed to cause a pregnancy.
Sperm would have a 5% probability of surviving more than 4.4 days and a 1% probability of surviving more than 6.8 days.
Of all couples trying to conceive: 30 percent get pregnant within the first cycle (about one month). 60 percent get pregnant within three cycles (about three months). 80 percent get pregnant within six cycles (about six months).
Conception is most likely to occur in the first month of trying (about a 30% conception rate). The chance then falls steadily to about 5% by the end of the first year. Cumulative conception rates are around 75% after six months, 90% after a year, and 95% at two years.
While some couples may conceive the very first month they try, most will take a bit longer, with roughly 75% conceiving within six months. 1 Those who are not pregnant after a year should seek medical assistance, But with treatment, if needed, the odds are still in your favor to get pregnant.
Many women become pregnant from having sex just one time without birth control. At least 85% of women, who continue to have sex without birth control, even just once in a while, will be pregnant within one year.
After unprotected sex, sperm can survive for three to five days in the female genital tract. Secretions from the genital tract provide nutrition to the sperm. The progressively motile sperm swims through the cervical secretions to the uterus, and then the fallopian tube to fertilise the egg.
