We had unprotected sex on the 9th of april but he did not cum but however I feel there might be pre cum involved I haven’t taken any pills or action on that later on the 14th of April we had unprotected sex again and before he could remove his penis a little cum was inside my vagina and then I immediately took an Ipill within an hour. My periods date is the 20th of April I usually get my periods 7-10 days early and I still haven’t got it. Do you think I should wait or should I take a test
