I have a Skyla IUD.. I've had it for about 7 months. All of this month I tried to check my strings but my cervix was so high and tilted up I couldn't feel anything. Now my cervix is super super low and tilted down (and closed) but I can feel way more of one string than usual. I can't feel the other one at all. Should I call my doctor or take a pregnancy test or go to the emergency room? What do I do? (I'm laughing as I type this because it's probably nothing) but it has me freaked out..
