What are the chances if you dtd on ovulation day?

Just started ttc and I thought dtd on ovulation day was the best possible time but I've been reading a bit and some say its better to do it just before ovulation. Asking this as we didn't have the opportunity on the other days but felt quite hopeful that we managed on the actual day. By ovulation day I mean the day the egg is actually releasing. Know when this is as I get a lot of pain on my left hand side when it's happening.
What do you think? :-)
Oh, btw, i'm in my forties, so don't have time on my side.

Good luck tober you just.might be lucky but if not, id say that next cycle start dtd often the days leading to ovulation, on ov day and the day after. That way your chances are higher
