Anyone with an extended cycle after taking Soy?

[Pretty_Peony]

Hello Ladies. I just wondered if anyone had experienced an extended cycle after taking Soy Isaflavones at all please? I have PCOS but generally my cycles are fairly regular and very definitely in the past 6-12mths they have been 34-36 days. Anyway, I took Soy for the first time this month, from CD3-7 and am now on CD43 with no sign of AF at all. I generally have a very clear AF coming pattern but I just haven't got any symptoms at all. So, I just wondered if Soy had made anyone elses cycle longer at all please? xxx
