Me and my boyfriend had sex for the first time three days ago. It was a mistake in that we were both intoxicated. He couldn't get hard because he was drunk so he didn't ejacualte and he used a condom. Still, I was very worried the next day. I spent the whole next day freaking out wondering I I was pregnant so I went and bought plan b to be extra safe. I took plan b a little less than 48 hours after we had sex. The day after I took plan b I started bleeding and it seems like I am on my period. I was expecting it to come around this time of the month. However my stomach has been kinda hurting me and I don't know if it is because I am nervous or if it is something else. Is this all normal? what is the likeliness I am pregnant?
