Am I 4dpo? More? Less?

Chels

In my fourth postpartum cycle (breastfed through a year - baby is weaning now & doing lots of solids). Had a miscarriage two cycles ago; last cycle and this were normal periods.

Is the 22nd accurate for ovulation based on OPKs? Or am I missing something?

Ttc & maybe just symptom spotting but have been soooooo nauseous yesterday and today.
