I was put on Marvelon for 6 months due to pelvic pain.My body regulated quite quickly to it.This month was my last month on it and I ended up getting my period a week earlier than I was sapossed to.This period has been extremely light and brown,usually it's really heavy (for some reason birth control made my periods even heavier than it was before).It's been 11 days now and it still hasn't stopped.I was put on anti-biotics a few weeks ago and I completely spaced that anti-biotics can make birth control ineffective,so there is a chance I might be pregnant.I've had a constant headache for the past week or so (not bad enough to take anything),my boobs are a bit sore.

I was wondering if anyone had this when they stopped birth control?
