Ovulation query! 1st baby but 2nd month TTC

Hi guys

I just wanted to ask a question as I’m not 100% sure when I ovulated. My peak day (according to the app was Thursday 18th June, we had sex everyday/every other day that week. If I ovulated late because I think I may have according to CM etc are we still in with a chance?! I think I might have ovulated around 20/21st June. We have had sex this week just only 1 time. Starting to think we may have missed it!

Thanks in advance I’m not very experienced with this kind of thing yet
