I just had the mirana put in 7 days ago. I have had stomach pains all week. It was put in on the first day of my period. They Couldn't Get My inner cervix to dilate for about 30 minutes. It was a very painful experience but I was glad it was over, but like I said since then my stomach has been hurting terribly. Last evening u was dizzy, running a fever, foggy, nauseated, body pains... it's been absolutely terrible. No fever today but cramps through my whole body and terrible stomach pains.
