I had sex 10 days before my period date.. I had un protected sex bt my partner had ejaculated inside bt not completely and not deep inside I had washed soon after we were done, and now I am 5 days late for my periods,my friend said that sometimes because of sex the periods get delayed, is there any chance that I might have conceived? If yes is there a way to get my periods without taking medications? :confused:

Yes, you very could be pregnant. No, there is no way to get your period without medication.

"not completely" and "not deep" does not matter.
