Me and my girlfriend had sex but realized that the condom broke and I came inside her. So I got her a morning after pill and she took the 1st pill with in an hour of it happening and took the second pill 12 hours later. Its been almost a month give or take and she's gotten a shot 2 prevent pregnancy but now she's telling me her period is late. Is this the effect of the pill or is she possibly pregnant? (note she's 15 and I'm 16)

The morning after pill will seriously effect the time of her period. ( but then it is not 100 percent effective either)

Only more time will tell, but most likely no she is not pregnant.

If she's on the shot and she took the morning after pill she should be fine. But don't be to sure. Weird things can happen. Just wait it out. Having birth control shots effect her period big time. When I was on the shot, I barely had a period. So don't get too scared.

If she's late for her period and you're concerned that it could be due to pregnancy, than she could try a home pregnancy test. Make sure she follows the directions on the box exactly. First morning urine is more accurate.

If you're still concerned after that than a trip to the doctor would be my next step.

Yes, the morning after pill and the shot can mess with her period, but, like the others have mentioned, neither the morning after pill or the shot are 100% effective against pregnancy, so there is a chance.

Just so you know, if she's not pregnant this time, and she's on the shot, even if you use a condom and she's on the shot, pregnancy can still happen. No form of birth control is 100%. There are people on this site that got pregnant using 3 different forms of birth control at the same time. It can happen.

So, if you're not ready to have a child, the only sure way to avoid pregnancy is not to have sex.
