So my partner and I had unprotected sex at one point, however, before ejaculating, he pulled out and we both saw that he did not ejaculate inside. However, being paranoid, a week and a half later I took a pregnancy test that resulted as negative. Since then, we've had protected sex once or twice within the same month. However, within this weekend, I should have had my period and it hasn't come. What do you believe the cause may be?
Anyone have any ideas? :-( please offer some sort of advice. I'm getting very worried.
