Has anyone had crazy long cycles with some brown spotting in between and found out why they had it? I think I have PCOS and am being referred to Homerton but I am going mad as I'm on day 71 and have had literally 2/3 weeks (broken up) of brown spotting. Has anyone had this type of thing - please let me know if just for reassurance but also if you might be able to shed some light on what's going on...thanks
