My boyfriend and i had intercourse. We used a condom, and he did not ejaculate. 5 days later I got my period, red, heavy flow. Now I've read that you could still get your period and be pregnant, i'm not sure if that's true. But my stomach has been feeling a bit weird. Bubbly I would describe it as. Cramp like. I have been stressing about it for a few days now, I have thought stress is causing this but I'm not sure. I will take a pregnancy test but I'm not sure when would be the best time. I also feel my heartbeat in my stomach, I read it's because of High blood pressure. but it can also be caused by stressed. Am i just stressing too much about it? Can stress cause all of this to me? Make me think that I am pregnant?
