Could someone take a look at my FF chart please?

[Francescal88]

So been TTC for past 6 months, have been having regular 30 day cycles until this month. Took FRER on day 28, 31, and ICs on days 32 and 33, all negative.

I know all I've really kept track of is my CM, but could anyone tell from my chart when my most likely OV day was?

Thanks in advance
