Just came in my girlfriend and am freaking out...?

Shes been on birth control for months now and she took her first pill of five that brings on the period yesterday. She told me its late in the cycle so its not as high risk. However, I dont care, the risk is still there. With that said, she is totally consistant with taking birth control nevers misses at 3pm each day. She just washed off her l area. Is on the way to the store to get a douche as well as the morning after pill which she will be taking within 1 hr after we just had . Anything can happen of course, but whats you guys vibe. I think from this point on Im not having anymore period. The temptation to do it condemless is just to enticing and I figure its not worth it. So I am hoping for the best, in the meantime, what do you guys think?
