So previous to pregnancy I O’d around CD 15-16

My son just turned 1 and I’ve had 2 cycles. Got my first postpartum period at 11months pp an second one came 26days later. They seemed to be just as regular as before pregnancy, I tracked with opks last cycle and never got a positive.

I’ve been doing the same but i ran out of opks😩

But it’s now CD17 and still not positive, I don’t think I’m ovulating. Ugh

There is a suuuuper small chance I’m pregnant based on my last hpt but I’m not certain and highly doubt it.
