Hello, my girlfriend and I had sex in jan. she took plan be and it was all good. Then again in feb. we had sex again and she took it again. After the second time taking it, her period moved from arjound the 20th to around the 7th. A few weeks ago we had sex and used a spermicidal condom and I did not ejaculate in her. Now her period is a week late and I was wondering if all the hormones from taking plan be twice in two months are just now settleing down and her period is going back to normal or is she pregnant. Thanks!

Plan B twice in two months can have her period off track for a couple months, even miss one perhaps. Also it has many side effects, some side effects also. I am sure you both read though all of the warnings in the paper work.
