I take my birth control pill religiously every morning at 7:30am. I started it a month and a week ago and ii didn't start being sexually active till mid third week,however we use a back up plan also(,condoms). I have headaches frequently and some nausea only in the first two week cycles of the pill and breakthrough bleeding. What may be the cause and should I worry? I reallyyyy do notttttt want kids. I'm a new wife and housekeeper. Thank you so very much for listening. Meg
