OK so my best friend Kaley was taking antibiotics while taking birth control and her and her boyfriend had sex without a condom on the 18th of Sept. He did not "pull out".
She was due for her period Wednesday the 29th, and they are always at the same time since she's on BC. Start on Wed, end on Sat. She hasn't gotten it yet.
How likely is it that she's pregnant? And should she take a pregnancy test if her period does not come by Saturday?
I'm so worried for her...
