Post IUD questions

So I got my IUD December 19th 2016, I was suppose to get it out the end of this year, (skyla) that did not go as planned because I got it out April 4th! I was very low and causing me to bleed and have cramps and pee every hour if not more. Well the cramping stopped, kinda and I know you’re suppose to get your period up to three months after. What was your first period like? Mine was just dark blood and didn’t really last as long as one of my normal periods but I did have cramps. Well, the cramps haven’t exactly stopped and they haven’t been “ period “ cramps. I know or have been told that it can change your cycle but I want to go deeper into this. I don’t have sex often anymore because me and my partner have been separated by long distance however, that make me more then sure I know when he had intercourse on the 2nd and 3rd of March, that it knocked my iud out of place. Two week later, March 14th I bled quite a bit for me on my iud, and had these odd cramps again. My worst fear went over my head as if I was pregnant, because when I got the iud I hadn’t seen my period in two years except a little spotting here and there not that I would have even noticed I was on it. which is was struck my interest to go to the obgyn and have it removed after they concurred it was two low after two ultrasounds, tummy and vaginally. Well lately, I can’t sleep on my stomach anymore, I pee very often, and I get weird feelings in my pelvic area like you blew a bubble and it popped it kinda tickles sometimes it kinda hurt, and I just feel a lot of pressure in my bladder and inside my uterus.I’ve had three negative tests and just gone to conclusion that’s obviously not my problem. However I know many woman who have had negative tests before, which is common. My questions are, what was it like for you after you got your iud out? Did anyone else feel this way? Has anyone heard or know a similar story to help guide me
