I Have An Iud In And It's Been In For

I have an iud in and it's been in for 3 years and I'm worried it may have moved. Long story short me and my bf were drinking and then came home and had pretty rough sex and I bled a little bit after and I'm I just parrinoaid ? I never get a period with my iud in sometimes I bleed after sex once in a while but this time I'm still spotting a little and it's been 2 days
