I've always had regular periods even after I miscarried (one year ago) and then a few months ago I had what was I guess a "fluke month" because my period was 12 days late but I never tested positive with a HPT and then eventually started my period. Anyways, after then, I haven't had my regular normal period with like 26 days between lasting 660-346-86827 days. Now it's more like a whole month between them and they last 8-9 days and even after the normal flow, I'll have random light bleeding (pinkish brown) with clear discharge with it for a few days after. What's going on and whaf should I do? What could be causing this?
