I've had experience with both..I started with the paragard. Tried it for almost a year. Then gave up. My periods were VERY heavy and long and I had spotting in between. Much stronger cramping with my periods too. And I had almost constant discharge, which apparently is common. Also, my partner could feel the string during intercourse, although it didn't bother him. I really wanted to make it work, but it wasn't good for me. On the positive side, there are no hormones and if you're happy with it, it can stay in place up to 10 years, making it one of the most economical forms of bc. And, if you decided to get pregnant again, it's easily removed.
Just had the essure procedure in July. No complaints so far! The procedure itself was a bit uncomfortable, had some cramping afterward, but that's about it. Had it done in an office setting, just local numbing, no sedation, went home and mowed the lawn later that night. So far I am very happy with my decision. I am 43 yrs. old and have 3 healthy, wonderful children. I'm happy to have found a permanent form of bc that was less invasive than a tubal.
As a 3rd option, has your husband considered getting a vasectomy?
Good luck with your decision.
