IUD pain?

Lucie🌿 • 25, atheist, vegan, engaged 💍🌿 I believe in the consciousness of sentient beings, and the respect they deserve.
I've had my IUD (3 year plan) since May. I spot every once in awhile, and still have periods. 
I've been getting a stinging, sharp pain internally- around my cervix. Getting this IUD put in was SO PAINFUL. Will it be as equally painful to remove it? Anyone else have pain with their IUD? I also have cramping during sex. It's kind of a pain in the ass.
