I had my period 24 days after my d&c. My period is 11 days late. I had dark brown discharge and cramps 8 days ago for two days. I have done several pregnancy test but they have all been negative . My periods where regulated by the pill before my miscarriage so not to sure of actual dates. Cylces are between 24-34 days but even if my cycle was 34 days I'm still late. Any advice ?
