Different colors symptoms and conditions

I have had this thing for 2 yrs now and gained about 20 lbs...also my dermatologist says I have this condition called melasmar or something like that...my entire face turned different colors due to the hormones. It looks like a few spots but if it continues it will cover you entire face and chest. I'm having my mirena removed asap!!!!

I am 17 and have been on ortho tri-cyclen lo for 2 years now I never really notice until I started having sex I wanted to do it for about the 1st 4 times than after that I never wanted sex, me and my bf had gone without sex for like 2months and every time he wants to do it I say I don't want to he says I never want to than it starts a huge fight, so we basically fight all the time. We have been together 11months yesterday. I don't know what to do I am really thinking its because of the pills, I get WAY moody, and I cry a lot. I'm always cranky and tired. I'm only 17!! I should want to have sex lots of sex not have no sex at all what is wrong with me? could if be the pills ? I have been on them for a long time now but I never really thought that it would be birth control to cause all of this.someone please reply.
