This is the first long-term contraception I've ever used. I used condoms in the past and now it's 19months since I got the Mirena inserted. The first month I got cramps and mild periods and then after that, I only get spotting lasting 5-6days, no cramps but I get mood swings and feel low sometimes. I also gained 7kgs within the first 8 months but now it's leveled. Generally, I like Mirena because I have mild side effects but I've noticed my sex drive is very low lately. I'm monitoring it for another 3months and if it's still low, then I'll consider taking it out.
