I'm hoping that I'm just being paranoid... I stopped taking Yaz after getting a little messed up on my schedule... I am now waiting for my period to start so I can start using nuva ring. My fiance and I do not have intercourse for fear of concieving before we are married (his parents are very religous) but we do occasionally fool around.. anyways my main fear is because my period hasn't come yet... and I was wondering if maybe it is due to my body adjusting to not being on the pill after 3 years of being on it.
