my body is acting weird

Ro
I got my IUD in December. Everything peachy, sex as usual, 20 days in I started cramping and I figured I was getting my period (I got my iud on my period). I've been spotting for like 3 weeks and I know that's normal so just using lots of little daily pads.
But, for the past 4 days I've felt like shit! Cramps, nausea, insomnia, 0 energy... I thought I was going to pass out while I was at work on Monday. And today was not easy either.
My guess is that maybe I'm ovulating, it kind of matches the days, but I need tips to feel better again. Feeling like I got run over by a truck every day is no-fun.
Has this happened to you? Any ideas? Questions? Comments? Concerns?
Anything would be highly appreciated
