Anovulatory Cycle?

[lb2006]

I'm looking for others who have experienced an anovulatory cycle. I've looked at examples of those on FF and see they can last all different lengths. I'm on day 30 of this cycle with no shift in temp. I usually show a shift on day 17 or 18....am I safe to assume this is an anovulatory cycle, or even a really delayed cycle?

I've had quite a bit of stress over the past two weeks & started marathon training 7 weeks ago....i know these can factor into it, but am looking for some insight.

I apologize if this seems like a dumb question, but this is the first time it's happened for me (have charted for 8 months)
