Me and my girlfriend had unprotected sex last july 16 2017 at around 1am. We bought morning after pills and she took it 2 hours after having sex. She got her period a week after taking the pills, which is exactly her expected day of period. (But im not sure if that was washing out of the blood due to the pills). After 6 weeks yesterday august 25 2017, she had brown spotting and today august 26 2017 she woke up at 5am with a really bad cramp but no period. Is she pregnant? Or what? What is the meaning of that? Thanks so much answer asap pls :(
