I'm 18 and me and my boyfriend had unprotected sex 2 weeks ago for a few minutes before putting a condom on. On Tuesday (3 days ago), I noticed light pink blood which I thought was my period a week early. This lasted maybe an hour. I've never spotted before and I have looked it up and saw this was a sign of pregnancy called implantation bleeding. I just finished my first term of nursing school and I'm really stressed out so maybe that has something to do with it. Me and my boyfriend are both not ready to even think about pregnancy and I'm really freaking out. Please respond soon. My period isn't due for another 4 days and the wait is awful.
