I have had an IUD placed since May of this year. Lately I have had a sharp pain in my lower left abdomin. I have also been experiencing slight flutters in my belly. To top it off my period was 18 days late, and it was just light spotting for 8 days. (Typically I have a normal cycle of 5 days). I see my doctor next Friday for an abnormal pap check up. But I was wondering if I should call and make one sooner.
