Should I take my iud out?

Ladies should I take my mirena out? Every time me and my boyfriend have sex the next morning I'll have the worse cramps ever for that day n I might spot and that's it! And sometimes when we have sex it hurts like he's pushing something in there! My boyfriend wants me to take it out n get another birth control but I had the mirena for 2 years and plus I don't want to become pregnant so fast ! Please I need feedback!
