Painful sex...is it my IUD?

Rachel
So I was a Virgin when I got married but I got my Iud in a couple months before I got married..anywho I've had it in for like 5 months so far and the sex is still painful. I don't know if it is from the IUD but I know that can be a side effect...I'm worried something else is wrong with me if it isn't that... Anyone else experience this?!
