When Should I Start OPK'S??

[IMPPEARL]

I picked up some OPK's today. Now my problem is when should I start taking them?? My AF has been irregular since my MC.

They have run as follows... 17 days, 34 days, 36 days, 33 days. I am currently on day 5 of my new cycle, and AF just finished her visit.

My Problem is that I don't want to miss O, I use to be 28 days every cycle...

Any thoughts??

Thanks for your input in advance!!

I start the minute the bleeding stops.. but I'm weird I would think around cd 10-12, throwing out that 17 day cycle.
