I had the Mirena for the full five years and loved it once I got through the first couple of months of side effects. I actually lost about 15 pounds and maintained the weight loss the whole time. My sex drive improved over what it was on Ortho Tri-Cyclen and its generic. Now I'm struggling since having the Mirena removed at its expiration. I tried Seasonale for one pack, but it made me loss sex drive and gain weight. Now I'm trying NuvaRing, but having terrible headaches and nausea. I would have another Mirena, but I really expect I will try to have a child in the next year or so, so I don't want to spend the money for a short usage. My sister also uses Mirena and she likes it as well as I did. The best part was light or no periods for the around four years!
