Well me and my boyfriend had unprotected sex about a month and a half ago(sorry I can't remember the actual date) and I don't think he ejaculated inside of me but he may of gotten some precum in me but the day after we had sex my stomach started hurting and I was tired all of the time. My stomach was hurting for a week straight followed by diarrhea. And a couple of days ago I started my menstrual cycle but it only lasted for 2 days and it was lighter than usual, and then today which is the day after I gotten off of my period I started getting these sharp pains in my stomach I am completely off of my period and I talked to my boyfriend about it and he is sure I am pregnant but I wanted to see what you thought first. I haven't taken a HPT yet though. But I wanted to know if you think I should take one or not. Please respond back
