question: My girlfriend has been really hungry for the past 6 days and a couple days before her period she took antibiotics for a UTI and then she started her birth control then took the rest of the antibiotics later that week and the memorial day weekend on Sunday we had unprotected sex (but used the "pull out method") and continued to everyday till that Thursday.  so is she pregnant or what because she is on her last blue pill for birth control tonight (monessa). She starts her green pills tomorrow.
