I've had nothing but issues with my iud. The first one I had maybe 5 months and I had my period the whole time!!! Then it just feel out. The one I have now I had my period for 2 months then tapered of to two week long periods every two weeks. Is this normal? Also I had light periods before that lasted maybe 4 days at its longest never had any cramping etc but now I have full on cramping etc
