So I got the IUD 29 january.. I was supposed to get a one month check up but i’m military so I moved bases and never got one. Recently I’ve had sex with a guy a few times. We would do it a couple times in one sitting and he would pull out but he never peed after he reinserted it. My doctor told me I didn’t have to do string checks so I never worried about it until I read posts on here about it. I checked after we had sex almost 2 weeks ago and i could feel them. That was the only time I checked my strings. I also only spotted for the first few months on the IUD and just recently stopped and haven’t had an actual period since the day I got it inserted. So I checked last night and today for the strings and I couldn’t feel them???? What does this mean? Could I be pregnant? I’m just really anxious because I really don’t want to be pregnant.
