Birth Control Advice

I really need some advice on birth control. I have been on two seperate forms of birth control since february, the first was the nuva ring, but I only haf it in a month because it literally made me feel like I was going crazy. I switched to a low-dose combination pill thag I have been on for almost 7 months. I have noticed that it has completely ruined my sex drive. I dont even think about sex anymore. Also, when I do have sex now it is near impossible to orgasm, which I have never had a problem with before. I want to get off the pill my option are limited. I am considering the copper iud, but I am extremely nervous about it because I already have heavy, painful periods. I dont know if I will be able to handle the extra pain and bleeding. I have my doubt with matural planning, My husband and I are nowhere near financially or mentally ready for a child. Any advice or experience with the copper IUD or anything Im mentioning would be really appreciated.
