Bbt chart

Hi ladies,

I could really use some help.

I typically have 31 day cycles.

Ovulation day either on cycle day 18 or cycle day 23 (cycle still 31 days).

My problem is I am now on cycle day 36.

I tested this morning with a digital home preg test (neg).

I did get a positive opk yesterday.

you think looking at my chart i ovulated on cycle 23 (based on temps) or what?

Normally, my breast are killing me before I start, but I just have cramping (like I did w my daughter).
