I am three weeks into my first pack of pills, and today I stopped taking them because of the severe headaches I have been experiencing. I rarely get headaches, and when I do I can treat them with advil....but three weeks ago (right after I started my first pack) I had a headache that lasted for three days. I thought I had a sinus infection, the headache was behind my eyeballs and throughout my forehead and temples. The headache went away but came back two days ago, and I still have it now. I am convinced it is from Yaz. I have not been able to find a birth control pill that doesn't make me absolutely psycho, and I was hoping Yaz would be the pill to work for me. I never experienced headaches from the other pills I was on, but these headaches are so severe and last for so long that I know it's more then just a common headache. I hope they go away soon...this pill is scary! And on I side note I also noticed I have NO sex drive...but that happened with the other birth control pills I was on too.
