I'm on day 22 of taking this darn pill. I haven't been on bc for almost 3 years and the only reason I am taking it now is because my doctor has me trying it for 2 months because of ovarian cysts causing stomach discomfort. For the past week and a half I've have intolerable headaches that seem to be increasingly worse. For the past 4 days I have started to have horrible lower back pain and I have been told this weekend that I have been biting everyones heads off for no reason. I still have stomach pain. I snap at everyone just out of the blue. I started spotting brown discharge in day 21 and I am so not feeling right. I'm glad I finally decided to look up this pill and read everyones comments. First thing tomorrow morning I will be making a phone call to my doctor.
