I'm scared...

Hi all. I'm a FTM and tomorrow I start bi-weekly transvaginal ultrasounds to keep an eye on my cervix. I'll have to go in every other week from 15-25w. I had a LEEP procedure about seven years ago, and so the doctors want to make sure that my cervix doesn't soften and open prematurely, resulting in a miscarriage. I know that my mind should be put at ease, because at least they're watching me and we have a course of action, but I'm still really scared. Anyone else have to go through this?
