Ttc after miscarriage

Bonnie
Hi all. I just had a natural miscarriage on Dec 29th. My doctor said we coukd try again right away. I have been using opk tests and so far no strong positive. I teat twice a day as I'm now on cd 23 and usually ovulate on cd 15-17 . Any ideas of when I should expect to ovulate? Anyone have gone through this that would have some insight. Thank you!
