I went from orthro trycyclen lo to Mirena IUD, I've had it in for about 2 weeks. So far I really cant tell any different besides feelings tired but I think thats normal with a 4 month old baby. I do feel bloated though you knowhow you feel right before you start your period, that feeling hasnt gone away yet. I hope that it does!? I guess all women's bodies are different so what is okay for one is completely different for another. I havent had any weight gain yet, but I havent ever gained any in the past either. Having it put it was simple, it felt just like a regular pap test just lasts a little longer to insert it, but I was really surprised.
Actually I have my brochure here with me that my dr gave me. It says only 3.5% at 3months had problems with acne then after 5 years 1.8% so the chances are very low. Mood changes 3m 2.5% 5 years less then 1%. Just an interesting tidbit after reading the IUD (Mirena) is more affective than a tubal ligation

wow. Now this is from the brochure: "Large studies have shown that Mirena has no effect on weight gain...Mirena contains levonorgestrel (hormone) instead of estrogen so you can be worry-free from estrogen side effects."
