Based on this when would you say I ovulated/am ovulating? I see my peak but would it be day of peak day after etc?

Ovulation normally occurs 24 to 36 hours after the LH surge.

Cd19 is your first positive so 12-48 hours after. Opks don’t confirm ovulation or dpo. If you want more accuracy add temping to confirm ovulation and you will know when you ovulated, dpo, luteal phase length (is from the day after ovulation to period which stays the same each cycle give or take 1-2 days. Average length is 12-14 days give or take 1-2 days.) when period is coming by temp drop or if you miss your period and your temp stays up then there is a chance for pregnancy
