Sometimes certain hormone treatments can make things like pcos worse. Well that's what happened to me I went hormonal as and started growing facial hair D: I am on AVA30 ed at the moment and it's pretty amazing :) Just keep trying new ones but remember that it can take up to four months for your body to become used to the contraceptive and stop messing around with your hormones :)
Mmm thats not good...try something different. there are a lot of options.
well maybe just use condoms then and stop putting yourself through all that. You should talk to a doctor who specializes in contraception for women because I'm sure there would be something out there that doesn't make you feel so crap.
