It is hard to say: It is hard to determine what is going on without knowing your cycle and more of your history. It is not uncommon, however to have a couple of months of abnormal bleeding or breakthrough bleeding following a miscarriage. Take necessary precautions during this time if you are trying to prevent pregnancy for awhile. You have said nothing to indicate you cannot become pregnant during this time.
