Birth control

I was put on birth control(Cryselle) almost 3 weeks ago. My doctor didn't tell me how long it takes to get in my system and I had unprotected sex last week. My friend told me it only took a few days and I believed her because she is on birth control also. The papers that came with them didn't tell me how long. Right after I had sex, I started getting headache's everyday. Is that a sign of pregnancy or is it just the pills causing them? And is how long for sure does it take to get in your system?

Birth Control does cause headaches. My sister got them all the time and stopped because of it. Some of them you can take and it will take a couple weeks to kick in. Usually safer to wait a month though before having sex un protected. You might be ok though. Just wait it out and I hope everything goes well for you.

It is recommended that someone starting on the "birth control pill" waits 2 full menstrual cycles before relying solely on it for birth control. Condoms are encouraged until completion of the second cycle. And remember that the "pill" isn't 100% effective, only 98% and doesn't provide any protection against STD's. Also when taking any antibiotics with the pill, it lowers the effectiveness and so does having diarrhea or vomiting as it is not absorbed in the system. To give the pill the most effective chance of working, one must take it within the same hour every day.
