switching from mirena iud to pill?

Hey so I have been on the pill before I got my IUD and I thought yeah it’ll be better but I’ve just been miserable the whole time. I’ve had my iud since January 19, 2017 when I got it inserted and its just constant pain that I have at my cervix its the same type of pain like when they inserted it. I would like to switch asap but I’m not too sure on whether it’s a good idea I’m sexually active with my SO we been together for 5 years hes my first and im his first too. My pains are pretty constant they feel like they come on really hard and have highs and lows every few minutes when I start getting cramps before on and after my period its gotten lighter since usually its max 3-5 days tops. My sex drive is there but it hurts in certain positions my so does feel my iud strings from time to time but it does get uncomfortable for me. I really wanted to ride out 3 more years but its just very uncomfortable the horrid pains I get in my uterus is unbearable to the point that I cant even get out of bed sometimes. Also having nausea and vomiting sometimes couldnt keep any food down. There were times my period was really late and doctors appointments a few times but everything looked fine. The doctor that I had insert it is no longer working there not sure if she moved or what happened but I’m not sure if I should do it or wait until my 2nd year or 3rd year of having the mirena in. If I do take it out I would like to switch to pills I was more regular and everything was a breeze my cramps wouldnt be nowhere near like this. I need opinions
