Long cycle, will I ovulate?

Lis

CD 24 and still waiting to ovulate... I'm hoping I will ovulate soon and this isn't an anovulatory cycle. 

Since I've gotten my period back after giving birth to my daughter, my cycles have been a little out of whack. Ranging between 33 and 36 days long. 

I've had next to no second line on all of the OPKs I've taken. Normally I have a pretty decent second line the whole time before I get the positive. So I'm hoping that's not another sign that this is an anovulatory cycle. 

I also started taking evening primrose oil this cycle. I have noticed an increase in CM but is it possible that it is delaying ovulation? 

Last cycle I ovulated on CD 21.

Anyone have any insight into what might be going on?
