I'm not sure that yaz will eventually affect everyone negatively but if you really read the entries here women are having these affects at all different times during their cycles as well as time that they've been on it ie; 3days to over a year before their negative symptoms start. I don't personally think one single BCP is worth the risk of these symptoms. You may feel women are exaggerating but they are not talking about pms they're talking about dibilating symptoms. Please be safe is it worth the risk or better to just switch. Don't just hope yore turn doesn't come
