I have been reading everyone's side effects. I know everyone is different. I have not experienced hair loss, bad acne, or horrible mood swings. I HAVE, however, gained about 40 pounds since having Mirena inserted in February 2007. My periods stopped after about 4 months; I would have the brownish discharge everyone else has spoken about, plus feeling like I didn't smell good. It did help with my migraines, but here in the last 3 months, I have been getting a migraine once a month, with severe pain and vomiting AND I have started to try and have a period again. This past week I actually did bleed enough to be a nuisance to me. I have had so many problems with birth control I am at my wits end. I am 34, have one child and 2 stepchildren; my fiance and I don't plan on having any more children, so I am seriously considering getting this thing taken out and having my tubes tied. I enjoy the fact that I don't have to think about birth control, but the weight gain among other things is just too much.
