Your periods get heavier. (never had it, that's what my doctor said.) I'm considering it too.

Are you refering to the "ParaGuard"..?
If so,maybe you can do a search on it.Maybe there is a forum somewhere in Cyber world about it..
Plus & minuses.

I will do a search on it myself & see.((gives me something to do))

HI.....I had the paragard for ten years prior to the mirena. My periods were regular but very heavy and lasted 6-7 days (very heavy for 2-3 of those days). I only had the mirena for 3 months before having it removed. It's been out for 3 months and I'm still battling horrific side-effects....the worst being muscle aches/joint pain and extreme hairloss. I believe I am currently experiencing the crash as some of the old side-effects have returned.....nausea, brain-fog, and depression. Hopefully it will pass once I start my period. Anyways, I had a paragard put back in once the mirena was removed and have had the new paragard for 3 months. I've had two periods on it. The first was typical of my old paragard periods...long and heavy. The most recent was only 4 days with one very heavy day and the rest of the days avg. or light. I've never had a period that short or light since before I had children....17 years ago. I'm anxious to see what this next one will be like. But, I will gladly take a heavy long period over the synthetic hormone side-effects any day! I will never and I repeat NEVER take any type of hormonal birth control ever again. My body has been through hell the past 6 months. I never had any health issues prior to this....

there are a few complaints about non hormone iud, but you should remember that the dalkon shield was removed from the market because it had horrible side effects, they tried to blame all the side effects of the string but later found out it was the iud itself.
there are some copper t blogs and videos on youtube. the hormones affect us just like the norplant that was also removed from the market. implanon is just like norplant it also goes in the arm and you can see the video on youtube. there is something called essure, everything is has hormones.

people i've met and including my mother in law who had it, had terrible problems from it. it scrapes your wall inside so you can't get pregnant. they bled a lot and had bad cramps, another lady i knew had to have surgery from it. but that is the copper iud, i don't know if they have a different one out now. all i know is i don't trust any iud now.
