Iud/ emotions

Avery

I got my iud about 3 weeks ago and today I was watching movies with my boyfriend and started crying out of nowhere like every 5-10 min. I also noticed that my boobs started to hurt like they normally do right before my period but I'm not close to being on my period... I just got off my period about a week and 1/2 ago. I was wondering if maybe the iud is effecting my hormones and making me super emotional.
