I had unprotected sex and took plan b. a week later I got a period. Then two weeks later I unexpectedly had to take plan be again and got another period after that. Three weeks later I got another period. It's been about month since my last period, but it is a few days late and I'm freaking out. Since I got the other two periods I can't be pregnant, right? I have also taken 3 pregnancy tests and they have all been negative. The only thing worrying me is that I feel a strong heartbeat in my stomach when I lay down that I have never felt before. Also my period is late but I do have a history of an irregular cycle. Any advice?

Because of the plan b your going to feel weird and you will be irregular. Stress just makes it worse, your fine.

As you saw, the Plan B will mess around with your cycle. It is mostly effective and it looks like you've used it correctly. That being said it is also not 100% effective so there is a chance that you're pregnant still.

Having an irregular period makes this difficult. Have you had unprotected sex, or sex at all, since your last period. If not then the chances of you being pregnant are low. Take the longest time between periods and if you haven't had your period after that you need to take a pregnancy test.

Good luck.
