Hi S.,
I have the other IUD. I can't remember the name of it, but it's the plastic one. Honestly, I have not had a period in God knows how long & don't miss it at all. =) So, don't be scared if you don't have a period. I was told my periods would be lighter than usual, but they just disappeared altogether after a while. I really don't know anything about getting pregnant w/ an IUD in. To be honest, shortly after, my marriage ended so I really haven't had sex much since then to worry about pregnancy.
Take care,
A.
