How many dpo?

Tiffany
Hey all. I got a positive opk on Saturday night the 19th. Would I have ovulated the night or most likely the 20th or 21st? Would I only be 6 dpo today and would I be feeling anything if I were pregnant? I had a mc in February and we've had trouble since. I had a saline u/s and hsg done 3 weeks ago. Starting clomid next cycle if it comes.
