It's a possibility you could be pregnant. Though if you don't want to be, you should consider an actual form of protection other than Plan B. It's not made to be taken habitually. I know one of the side effects are that they can make your periods more irregular so it could just be your body adjusting to that. Like ariana said, try testing and if it's negative wait and retest. You can also go to your doctor and ask if they would blood work.
It's just been spotting since the unprotected sex. But it's only been a week since we had unprotected sex. The cramps are on both sides, not just one. So i'm not sure exactly whats going on.
im a little bit confused, have you had a period since the unprotected sex or just spotting? obviously anytime you have unprotected sex you could be pregnant. the spotting can indicate lots of things. is the cramping on one side only? if its been 2 weeks since the unprotected sex you can take a test now. if its negative wait several days and try again.
correction: he "came" inside of me on 5/4. not the day after my period...
