I had my IUD insert 6wks after I gave birth to my 3rd baby. its been 22mths now. been having pregnancy-like-symptoms since last yr. didn't have menses ever since insertion. did pap-smear check last yr but I am not pregnant. again I am having the same symptoms now (around the same timing as last yr). now, I am feeling nausea, giddy n even vomited (just like morning sickness). I just wonder is there other Mirena users experience the same way?
