I started Yaz 3 or 4 months ago and I was on Yasmin but the doctor changed it and I was sexually active with no other birth control. Two months into the Yaz I decided to skip a period and just take the next pack skipping the 4 sugar pills. I started to notice my breast started hurting rather bad and still do, then I had bad lower back pain for a few days. A couple weeks later ive been nauseous every night for 6 weeks.  My blood pressure has dropped to around 96/76 sometimes lower to the point I almost faint. But I still had my period when I took the sugar pills it took two days to start and was light at first and got a little heavier but was done in 4 days. I've been avoid actually testing thinking it's side effects from the pill and not to worry but I gotta ask what other women advise.
