I've been taking the pills for 12 years. I stop taking the pill 2 week before my period ( green pills). I do want to get pregnant, I had unprotected sex on Monday and Friday. I notice that when we finish having sex on Friday I had a light bleeding. And the next Monday I started my period (very light bleeding). I'm very exact and I usually start my period on a Thursday (for years) now I started on Monday, can I still get pregnant? What are my chances, I really want to be pregnant?
