I am almost through with my first pack of pills (Yaz). The first week was fine than I began having what felt like sinus headaches, stomache aches, loss of appetite and fatigue to the point where I am exhausted at night and can barely get out of the bed without feeling sick. Is this normal? should I just continue to take them and hope the side effects subside in a month or two or should I contact my doctor?

Those are all normal potential side effects. But if they feel extreme to you, or if they're interfering with your ability to function in your daily life, then you should definitely call your doctor.

My friend felt the same way. She was so tired (and moody I'd say!). She switched pills and she is just fine now. Hope everything works out for you.
