I got the essure procedure done in March. For me, it was a breeze...in and out of the office. I even got to watch it on the monitor as the doctor inserted the coils. I think it helped that I had delivered my 3rd child 6 weeks before so I didn't experience a whole lot of cramping like some because my cervix was still dilated. I haven't had any problems (although it's only been over a month). The only thing was that about 2 weeks after when I tried doing sit ups I could "feel" the coils and it was hard for me to do any ab workouts. Now I'm fine.
My friend has had the mirena for about 4 years now (you have to replace it every 5 years). She loves it. It tricks your body into thinking you're pregnant so you pretty much have the symptoms of how you were when you were pregnant. The thing I liked about what she told me was that she has not gotten her period since she got it inserted. I would LOVE to have that. You still get your period with the essure. I chose essure over mirena because it's a one time deal and it had a higher percentage of preventing conception. Also, Essure is a permanent procedure so you have to make 100% sure you don't want to conceive anymore.
Your ob/gyn office should have pamphlets on the different types of birth control they offer.
I forgot to add some of the negatives when I wrote last time. With the Essure, I wasn't told until AFTER they inserted the coils that I can't get any MRIs done because of the coils. If I get anything done or any examinations down below (Pap Smear, ultrasound, etc) I have to inform them that I have the Essure. Had I known all this BEFOREHAND I would probably have gone with Mirena (my second choice). I'm ok with having had the Essure done I guess esp since it's not hormonal and it's pretty much a sterilization procedure. My 2 other friends who got the Essure done said they've experienced bad cramping/heavy menstration since they got it done. I'm only on my 2nd day of the second time getting my period since delivering my son and getting the Essure done and I haven't noticed anything different than before. Hope this helped!
