For the past two months, a week after my period, I have been getting brown spotting. The night before the spotting occurs I get headaches and feel sick. I take my birth control (
YAZ) as directed and I have been on it for about a year and a half. The spooting only last about a day or two, but I have never had it do this before. Is this normal? I have heard a lot of bad stuff about Yaz also, should I change birth control?
