Whay do you think? Grateful for opinions.

Hi ladies! I'm still new to TTC so plz excuse my naivety. I had a really late ovulation this month; CD24. I was just expecting to not ovulate at all, but on Thursday, I had really heavy EWCM, so I decided to test with an opk and it was almost positive; I could tell ovulation would occur probably within 48 hours. So, I BD'ed around 12:30 pm on Thursday. I tested 12 hours later and definitely got my positive opk; however, since the positive test, my bf has not been able to cum. Is it still possible to get pregnant with late ovulation and the fact that we BD'ed 12 hours before I got a positive opk? Thanks!
