Hi, im 25 and was ttc from Nov06 without success, had a suspected miscarriage in Jan 07(had excessively heavy bleeding). I went back on the pill to give myself time to sort my head out. Got my next period as normal on Feb 10th 07 and again had really heavy bleedin and given tabs by Dr to help calm the bleeding. Then i started spotting after sex on 21st Feb, it is really dark and sticky, i have never had anything like this before and have been on the same pill for 10 years (having occasional breaks during this time).

Does anyone have any idea what this bleeding could mean and should it be this dark?
