I started taking YAZ two months ago and experianced no sickness or anything irregular except that instead of my period being three days long, it was 9...but I started the pills in the middle of my cycle which explains the irregular period. But this month, I have not gotten my period and it is 9 days late. The last four active pills made me sick to my stomach about thirty minutes after taking them...then I started the inactive pills and did not get my period. When I started my next months supply, the active pills did the same thing, I keep getting sick after taking them. On top of all that, I keep experiancing random sickness throughout the day. For example, I will be sitting at home, feeling fine, then all of a sudden I get the urge to vomit. Once I vomit, I immediately feel better. I also gained some weight, which I contributed to the birth control because I had never been on birth control prior to the past two months. I also have frequent unprotected sex with my boyfriend. I took a home pregnancy test which came out negative...so I am out of ideas of what could be wrong...any ideas or advice?
