I've been on my birth control (Loestrin 24 Fe) for 7 months know. I had unprotected sex with my Boyfriend. A week later I got my menstrual cycle early but I'm not due for my period for another two weeks. Does this mean I might be pregnant.
No it doesn't indicate pregnancy. You are taking birth control to prevent ovulation. So while it wasn't protected sex against STDs (no condom) it was protected sex against pregnancy (birth control pills).
Sounds like break thru bleeding. It can be common for some women taking birth control.
