What are the chances?

We had unprotected sex on the 13th (accidentally at 4am both not thinking much about it until he finished and I realised he wasn’t using a condom 😨) supposed to ovulate today 16th. So it was 3 days before ovulation was due. What do you think the chances are I got pregnant this month? I’m 41 btw so my eggs are probably not so great anymore.
