Out of curiosity.. please help!

I posted yesterday about my positive ovulation tests but like I said in that post, these are my FIRST EVER positive ovulation tests since I have PCOS and anovulatory cycles. The first picture I got Thursday night, second picture I got friday morning and third picture I got friday night. I tested this morning and they're definitely going back down because the test line was now slightly lighter than the control line, definitely negative now.

My question is.. we BD Thursday night, friday morning, friday night and also tonight. What do you think our odds of conceiving are?
