Copper
"I've had constant spotting for the last 3 1\2 months after I got it placed 4 months ago, and when the spotting stopped 2 wks ago and I have not had my period since having it placed, just spotting. I did talk with my reg doc, and she said a copper IUD can cause a hormone imbalance, and this is prbly why I haven't had my period and have had hot flashes, the way to fix this I would have to go on BCP, it completely defeats the purpose of having a non hormonal IUD.I have constant cramps, pain during intercourse, gained 20 pounds (in 4 months), hot flashes, I smell like stinky fishing bait ,and I'm positive I can feel it when I move the wrong way. I'm sick of smelling like an fish all the time. I need it out ASAP."
