I got Mirena in May 2009 after I had my second baby in February. I really like that I don't have to think about daily or monthly BC, but I hate the side effects. I've gained almost 10 pounds since May, and I leak vaginal discharge like crazy. Every morning when I wake up, I can feel it pool out of me and it does it at other times too --- so annoying. I also was enjoying the fact that in the first month of having it, I did not get a period. But that soon changed --- I now get periods that I can't even call periods; it's either spotting or heavy discharge tinted w/ blood and it comes and goes as it pleases, there is no pattern and no warning. I'm not sure what I'll do at this point. My GYN said it can take up to a year to regulate, but if it stays like this, I may switch to something else.
