Ovulation after miscarriage.

Hi all, I recently experienced a miscarriage at 6w0d. I bled heavier than a period for the first 2-3 days and passed some tissue. Since then (another 3-4 days) I’ve continued to have very very light bleeding (just wipes pink, panty liner only). Still much “longer” than a normal period though.

In anyone’s experience, when did ovulation occur? I’m guessing it won’t be as soon as the typical 2 weeks if I’m still having some light bleeding. My doctor said that Fertility is somewhat increased post m/c because of hormones and the fact that the cervix is more open, so I’d really like to not miss this chance just in case. When was your first ovulation? When should I start testing? Currently on CD 7. TIA!
