Reassurance/advice on BD

Hey all, after a bit of reassurance/advice.

Been using opks to track ovulation and got my first high/peak yesterday which continued today. Definitly ovulated as had some pain earlier today.

So we BD Thursday and again Friday but on Friday he didn’t finish inside me (sorry if tmi). I’m not sure we’ll get a chance to BD again tonight. Will tomorrow be too late? What are our chances?

Just worried as I’m 34 and trying for our first and worried that it might take a while or might not happen.
