Husband has covid and ovulation today

This month we decided to do the smep and we DTD yesterday as got a positive opk and I’m pretty sure I’m ovulating today but because my husband has just tested positive we won’t be DTD for the rest of this cycle. What are my chances of conceiving for DTD 2 days before ovulation ? This was our 5th month trying :( I didn’t realise it would take a while to fall pregnant , with my son who is 2 we got pregnant first try
