Long story short: I'm on the pill, but I haven't been taking it at the same time every day, I was suppose to get my period today (6/13/12) and a couple days ago, Saturday the 9th, I rode my boyfriend's shaft, with no condom. Before I checked for precum, and he was completely dry. I got off when he said he was ready to cum, so he did not cum on me or in me, and there was no precum, because I felt and checked...but I didn't get it today..? I am 20 years old, and I just left him today for the whole summer so I've been really emotional/stressed. Could that affect it? I'm really scared, please help!! Thank you!!!
Do you have regular periods? If so you probably weren't ovulating during the time you had sex, so you are possibly in the clear. I don't want to say that you are completely in the clear, but you could always buy a home pregnancy test, but I'm in the same situation as you and am scared to death that the results could be positive!
