It has been 2 months since my IUD insertion. I was prepared for heavy bleeding and bad periods, but no such thing happened!
My first period was a surprise, as I had absolutely no cramping. I wasn't even sure it was time except for a telltale blemish on my chin and a bit of tenseness due to hormones. This was certainly a pleasant surprise. The only day I could really "Feel" my period, was my heaviest day (usually day 2) I felt a bit hot and bloated. Had I known my periods would be so easy, I would have done this years ago!
The only change (besides the absence of pain) was my period came faster which seemed to be caused by no clotting. Period #2 was even easier, as it was lighter and lasted only 4-5 days.
I did notice for the first month, that climax during intercourse made me very sensitive. For the first couple of times it was a pleasure-pain, almost like a mini-cramp. (It was not at all unpleasent) lol
