Tuesday, August 17, I had unprotected sex with my boyfriend. I started my period the following morning. My period lasted about 7 or 8 days and then it stopped. About a day or two later I started bleeding again. This went on for 19 days straight. So after it stopped I had about a day, maybe 2, and now I'm spotting. It is really light and then at about the middle of the day it went to about a medium flow and now I'm back to just spotting a very light pink, tannish, or brown color. I'm really concerned that I am pregnant. I've been feelings really hot here lately, for about a week and a half, my breasts are sore, I frequently go to the restroom, and I've gained a couple pounds. I have not taken a pregnancy test yet. Do you think there is a possibility that I am pregnant?
