"i have been on yaz for a little over 4 months and have been surprisingly happy with it. i had mood swings and was pretty emotional for the first 2 months but it really has gone away. i was also bleeding a little irregularly at first but that also went away. the only complaint i have is that it has killed my sex drive and is causing problems in my relationship. i can&#039;t really ever get wet anymore which never used to be an issue. for that reason, i am switching to paraguard which is non hormonal. i really wish it didn&#039;t cause me that problem because otherwise i love it!"
