STOP READING THE REVIEWS on the internet. I had ablation done 5 years ago and couldnt be happier. I had excessive bleeding after 3rd child (and 5th pregnancy) with cramping and other uncomfortable symptoms. I found out I had anemia when I went to donate blood so the doctor said this would help.
Now, I chose not to have tubal ligation because my doctor didnt think it was necessary for me. Why are you having this done? My friends who chose as birth control have reported cramping that is worse then their normal period cramping. I would ask the doctor the expected benefits and worst side effects that could be expected from both procedures.
I have had no bleeding since the ablation and NO cramping either.
Good luck!
