I started taking the contraceptive pill 2 weeks ago and had unprotected sex on the 7th day when I think I should have waited until after the 7th day. I don't know if it's too early to develop symptoms but I've been feeling nauseous of a morning, my boobs are sore, I'm having menstrual cramps and I feel like I'm getting the flu. I was told by the doctor as long as I took the pill (Micronelle 30 ED) within 12 hours of the same time every day I would be protected but now I'm worried?
