Questions about Paragard???

Nikki
Can anyone please enlighten me about their experience with ParaGard? I had Mirena and it gave me chronic migraines, so I had no choice but to remove it. So now I'm considering ParaGard because of it being non hormonal. My main concern is that my original reason of being on bc is to prevent my severe cramps and heavy bleeding BUT I read some reviews that ParaGard gives you heavy bleeding and cramps throughout your time of using it. 😩😩Is it the same experience for everyone using this particular IUD? Does the heavy bleeding contribute in the beginning stage of getting the IUD or its something you have to put up with for the remainder time of having it?
