Hi! I'm currently taking the yaz pill and having sexual intercorse. I know it was really stupid but instead of taking the blank pills in the yaz box to finish The pills I directly started a new pack because I wanted to skip my period. Now I am at 2/3 of this new pack and I started to have a lot of cramps and mood swings last week now there is this brownish blood coming out and I don't know what to do. Should I be worried ???
