I had my son 5 months ago and had my Mirena put in at my 8 week check up. The day I got it in I hurt so bad and siting down was out of the question!It honestly felt like it was crooked or put in wrong. So I called my doctor office and of course like always no one ever called me back, but luckily the next day my body adjusted to it and the discomfort was gone. But I bled for oh my goodness, i want to say about 6 weeks after that! it was a drag! But now my periods are back to normal , I haven't noticed a difference in decrease yet ( sadly) in fact they may be a little bit heavier and longer. ( or it could just be that they seem that way cause I had a 9 month vacation! I also haven't noticed any horrible side effects other then just one. Sounds funny because im only 21 but i seriously feel like im going through menopause! Has anyone else felt this way?? I sweat in the middle of the night but am cold . Sometimes burning up hot when everyone around me is freezing cold and begging me to turn up the heat. Im boyfriend will probably tell you ive been mood swinging , maybe I have, i cant tell , right now im planning our wedding and raising baby ,I don't have time to tell, or know if anything ive been feeling is from the IUD or just stress from wedding planning. Now last week and the week before that i had a constant headache but again maybe be stress related. And as for depression, I was diagnosed with that when I was i think 16 and take zoloft for that so I don't have any problems with that. But I just want to know if anyone else is experiencing menopause like side effects?
