Ovulating CD23-28? (34 day cycle...)

TTC since the end of November 2009. (formerly on pill for 5 yrs)

Cycle was averaging out to 34 days, but this last month it went crazy and I bled for 3 weeks. Could have lost an early pregnancy, or it was just hormones.

My doctor have me Provera, a hormone drug, and it should regulate my cycle to 30 days after a few months of taking it.

I noticed this past week that I was seeing changes in my CM...as if I was ovulating! It would be CD23-28 that I noticed these changes. I figured it was too late in the cycle to be ovulation. Then again, if I knew my ovulation dates as well as I thought, I would be pregnant by now. So it could be that I ovulate late in my cycle.

I went through my notes on my CM and realized a pattern! From Janurary through May, I charted my CM being EWCM and then Creamy on CD's 23-28.

I am thinking this is no coincidence...and I either A) ovulate late and this is my 5 day window, rather than days 14-19 as the website predicts...or what most women do with a cycle length of 30-34 days...or B) I have not been ovulating at all, and the CM is just my body's preparation for my period...(since it comes about 6 days after I notice the CM changing...)

Very confused...but hoping that it means I ovulate LATE and can figure it out. We BDd during these days accidentally this cycle! But not sure if it will matter since I am on this medicine that starts my period in 3 days...????

FX!!!
