I had a quick question in regards to Mirena.

Jesska
Hi! I'm Jess and I'm quite new to the IUD stuff, haha, I thought I did all my research but I'm just a tad bit worried as I haven't seen anything about the "problem" I'm having. 
As they requested, I had my IUD put in during my period, it was the second day of (sorry if TMI), and since having it put in, my period has since stopped? Idk if that's a normal occurrence or what, but I just wanted to know if anyone else experienced this?
I get that I've had it only a few days, but between the emence pain (after insurtion) that is now slowly dying down, I was just a tad bit worried that something could be wrong. Trying not to be an IUD basher as I was really hoping this was the right option for me. 
Someone please set my mind at ease?!! 
Thanks!
