Can precum on the outside get you pregnant?

Hi Aunty Vadge,

My boyfriend briefly touched his penis to my clit and outer lips, and precum may or may not have been there. Does this increase my chance of getting pregnant? What should I do?

Hello S,

This is very low risk. Pregnancy needs sperm to get inside the vagina and travel up to meet an egg around ovulation. And brief contact with your clitoris and outer lips, with maybe a trace of precum, is very unlikely to do that.

It’s not quite zero, to be straight with you, because precum can occasionally carry a little sperm, so if fluid got right to the vaginal opening and you happened to be near ovulation there’s a small theoretical chance — but from what you describe, outer contact only, the odds are tiny.

If you want extra peace of mind, emergency contraception is available over the counter and is an option — levonorgestrel (e.g. Plan B) works best within 72 hours, and ulipristal (ellaOne) up to five days — though for external-only contact it’s likely more than you need; it’s there if it eases your mind.

Where you are in your cycle helps gauge the risk too, so if you were nowhere near ovulating the chance is lower still. And if your period is late, take a home pregnancy test for certainty.

For next time, condoms or another form of contraception take this worry off the table. And condoms also protect against STIs — and if you’d like to talk it through, a sexual health clinic or your doctor is a great, judgement-free place to do that.

Take care,
