<s>[INST] Hello, I know this is probably unlikely but I heard it happens. I had sex while I was on my period 7 times and I had stopped my period three says early, he had spermed inside me each time we did it. By any chance could I be pregnant? Thank you for your time. [/INST] HelloThanks for writing to us with your health concern.Pregnancy while you are menstruating is virtually unheard of.For pregnancy to result, fertilization of the egg by sperms should occur.For this to technically happen, the female should be ovulating.Ovulation , that is, release of a mature egg, occurs each month during the middle of a cycle.If your cycle is of 28 days, it occurs around day 14.Hence, during periods, this is impossible.Anecdotal reports exist, but then thats rarest of the rare.The ovum also survives for no more than 3  days inside the peritoneal cavity.Hence, please stop worrying.Even if ejaculation occurred inside , there is no way you can get pregnant.So please stop worrying.Just to be on the safer side, you can go ahead and take a pregnancy test if you skip your period / have an altered period.However it is quite unnecessary.In future, please have protected sex so that infections / pregnancy can be prevented.All the bestPLease feel free to discuss further by writing in anytime at - </s>
