I had unprotected sex on the 10th of Sept. He didn't inside, but i'm worried about pre-. I took the morning after pill less than 48 hours later. I started heavy bleeding on the 16th of Sept the was exactly like my normal period but just a bit heavier on the first 2 days. It lasted all five days. I'm waiting on my next period to come in roughly 6 days and i am bloated. I was wondering if theres a chance of being pregnant. I haven't had sex since that one time.
