Period/IUD

Lilly
So I was on the depo shot for around 2 years, I stopped in June last year and I got my IUD placed in July. I have the paragard and I just started cramping and bleeding on Sunday. This is the first period I've had in 3 years if it is my period. I can't feel the actual iud but the strings are lower than they've ever been. I have an appointment for the 22nd but just wanted to see if anyone had any info. Could it be coming out? Or am I just over exaggerating?
