Do you get PMT with the brown/yellow loss?- as what is happening to me is that every day I wake up with PMT which is horrendous, and I would expect a period to start, but all I get is a tiny brown stain and more PMT. I wonder if I will be a 70 year old lady still with this problem! I imagine PMT for ever!
My last period was in early June so it's delayed now but I think it has been trying to start for 10 days.
