I am sure like anything else (like pregnancy) some are lucky, some are not. After reading this, I cant say i consider myself super unlucky! But, I have had Mirena in for almost 2 years, and have an appt. to have it out in 3 days...
I basically feel pregnant. Never have periods any longer, horrible cramping though I never had PMS, now have ovarian cysts on both sides, very tender breasts, smells make me sick, very picky about what I feel like eating or not and very tired. The lower back cramps get so bad they make me feel sick. I go through periods of random and constant spotting, then nothing. It is very disruptive in our sex life, though another problem I don't seem to have is diminished sex drive (but, pain, spotting etc has affected it).
I cant say I have had weight gain, though I am very active so that helps. But, I can say my body has changed - my breasts are larger though my body fat % is under 15, and my jeans feel much tighter in the hips and butt with no real weight gain. I feel like I have been moody as well, and almost felt depressed, but had some real stress so I didn't attribute that to Mirena.
The first six months was crap (discharge, cramps, spotting, irregular or no periods), but I really felt like it may take time. I hadn't had kids, so yes, for me it hurt very much getting it in, and I have a pretty high pain tolerance, though I am sure it varies for everyone.
I guess it is one of those things, maybe too good to be true. I am glad I tried it, because I do love the idea of it but I am done! Kind of is weird that they don't know 100% of how it works, different for everyone but I can tell you that until I got the cysts, I def. felt like I still ovulated.
The pain was so bad getting it in, I am nervous about getting it out! The "thread" or whatever is no longer beneath the cervix, though the sonos I had for the cysts show the placement is fine...if anyone has gone through this, let me know!
it comes dwn to what others say - if this seems to be the best alternative for you, try it, give it a bit of time, but LISTEN TO YOUR BODY. I wish I had it out months ago...
