Ok so here goes.. I have always had 27-30 day cycles. I have never been officially diagnosed with pcos, just thought I had it because of facial hair, weight gain and it took 3 years of trying to get pregnant before. I had what I thought could be implantation bleeding on the 20th, my period was due on the 31st. Here I am, 12 days late with 3 Bfns, tired, beyond crampy, nauseas and cranky. What gives???
