Here is some basic information about the birth control pill: http://www.teenhelp.org/forums/f6-se...rol-pill-pill/

The most effective means of taking it, is by following the instructions perfectly. I would make sure she is talking to her doctor about skipping her periods (to be on the safe side), but I would assume it's not affecting the effectivity of the pill itself.

As for 'pulling out,' I don't consider it a particularly useful method since there is still sperm being released before the male ejaculates. She is still at risk, seeing as it only takes one sperm to impregnate her. Despite this, my unprofessional opinion would be that there is a slight reduction in pregnancy risk. I wouldn't trust this though. The most effective contraception is combining the pill and condom. If you're worried about pleasure, you can try the ultra thin kind, or maybe the ribbed kind. Experiment with different ones.

Lastly, I would never trust just one pregnancy test (especially if it's just bought from the store). Perhaps you could try another in a little while. Or simply ask her to stop purposefully skipping her period to see if it comes.

Again, I would encourage you (and her) to talk to your doctors about this. None of us are professionals, and I do think you might gain from speaking to one (especially about this birth control skipping periods thing).

Hope this helped a little
