I've had mine for almost 2 years now. I noticed the other day my string got A LOT longer. I was wondering if there is any cause for concern. I mean, did the IUD move out of it's place or is it something else. Also, I'm 3 days late so far....I have a had pretty normal periods the whole time and if they messed up it was always early...never late. I didn't think there was supposed to be changes like this going on into my 2nd year with it. I can't really feel my cervix b/c I can't reach that far. Should I call my dr, or just chill out about it?

Thanks!
