Plan b I’m worried

I had unprotected sex without birth control two weeks ago, an hour after I took the plan b pill. A week later, I began to bleed very heavily for almost three days when my period wasn’t due for another three weeks as I had just gotten off my period the day before we had sex. I was two days before ovulation when we had sex I found out and although I did bleed and take the pill within the proper time frame, I’m still very paranoid about my chances. I’m bloated and idk if that’s stress, the pill, or the fact that my real period starts in 9 days, but I just wanted to hear from someone who might have more knowledge than me or someone who has a story they can share that might give me some better insight on my situation.
