hi, im 19 years old, my las period was last march 13, and supposedly my next period would be april 6 as expected.. but on april 3 me and my boyfriend had sexual intercourse, and using withdrawal method..... now I experienced abdominal pain but its still mild.. Im so worried that I may be pregnant since I have missed my period for a couple of days.. during our intercourse, my mucus is so sticky that I think Im fertile.. would it be possible that I may be pregnant now even when my boyfriend didn't let the sperm in? Now im not experiencing nausea and vomiting, no spotting,.. Im very worried with my condition.. Should I wait for my next period a couple of days? pls I need a response regarding my questions..
