On May 4th had intercourse part way through realized the condom slipped off and was inside me, the person I was with did not ejaculate and I took the Plan B bill around an hour later. I haven't been on birth control in over a year since I was no longer in a relationship (foolish I know). Met back up with this person one thing lead to another. My last period started on April 9th and lasted till around April 13th. For the past 2 or so days I have been extremely nauseous to the point where I am vomiting even if there is nothing in my stomach (usually late at night or early in the morning). I know it takes at least two weeks for symptoms to show, I was wondering would be my risk factor of being pregnant? I'm freaking out, and there is no one I can talk to about this (my family is extremely religious).
