Paraguard month 6

This marks my 5th into my 6th month if having the paraguard and things are weird. I bled for 2 weeks starting at the end of August and then I got off for a week and spotted for a few days. Then was off it again. I am now experiencing the normal awful cramps associated with my period but I'm not bleeding at all. I did have unprotected sex with my boyfriend, in August and twice in September when he was in town. He pulled out every time so now I guess I'm just worried if this weird spotting and random cramps/long period is normal or if I'm in trouble?
