Is it possible that iam pregnant if he rubs precum on the lips of the vagina then we have protected sex?

It's possible.: Pre-ejaculatory fluid may contain sperm, so you could be at risk. If possible, avoid any contact of the penis with the vagina, thighs, abdomen unless the penis is fully dressed in a condom. I have seen a patient who got pregnant when her partner ejaculated on her thigh. And one woman got pregnant through underwear with no penetration at all. Sperm swim well. Be careful. Lgromkomd.
