I just got my Merina yesterday. Insertion wasn't NEARLY as bad as I had thought it was going to be. I've also never had children. It was kind of like cramp, I suppose.
I went with the hormonal one because they say your period can completely stop. That's a side effect I like
I was also informed that with the non-hormonal, copper one, the body can reject it easier and you can bleed more. That one I didn't like. So I went with Hormones.
Hopefully the cramping will stop soon, but it's only been one day. She left the string rather long, hopefully that won't get in the way of sex once I feel like having it again, LOL...
For those of you with Merina, how long does the tenderness and soreness usually last after insertion? This thread has been really nice to read, it's answered a bunch of questions
