Hello- I had unprotected sex the third day of my period- and I didn't take plan b, but my period continued. I then had unprotected sex the day after my period finished and I took plan b that afternoon. It's been a week and a half since I took plan b and I am bloated and my breasts hurt- I know this must be the progesterone- but it's been about three days and my next period's not due for another week and 3 days. Is this normal?? I do feel like I will get my period soon- but I don't know the difference if I were to be pregnant.
