I've had the copper IUD for almost 2 years now, and my periods are more like a 23-25 day cycle but they've pretty much always been regular. Heavy and painful cramps, but regular. My period 8/10 days ago seemed a little lighter than normal, little less cramping. Then today I started very lightly bleeding, but I've had headaches last few days, swollen breasts, cramps, and felt very hormonal.

do I need to see a doctor? Or just wait and see next month.
