If I have two period in one month I can be pregnant ??

I'm going through a similar situation I took the plan b pill 3 weeks before the 3rd of may , may 3rd I got my period thank god normal cycle. That Saturday I had sex with a condom but it broke he pulled out though but just to be safe he got me the plan b pill that Monday . May 18th I got my period again and I'm nervous as to what's happening I'm super new at this lol ugh

I doubt it! If you are having your period, you can be pretty sure that you are not pregnant, and the fact that you took plan b has a lot to do with the fact that you had 2 periods in on month.
I am not a doctor, so if you really want to be sure you should make an appointment with your family doctor or your Gyn. to be examined and take a pregnancy test to be totally sure!
Good luck to you!!

If you have a period its a safe bet you're not pregnant. All that is wrong with you is you took plan b. It will mess with you're cycle for a few months. I'd suggest you get on regular birth control so you don't have the shock to your system that plan b causes.
