HELLP!!!

Hey ladies I really need some help. So I posted a few days ago about my first first IUI is Monday... well I got high fertility Friday night and Saturday morning then received my peak Saturday around 3-4pm. We BD last night when I received my peak but I feel like we should tonight as well however what if I don’t ovulate until Monday (IUI is set for 7:30am) and if we BD tonight I worry how his count will be Monday morning. I mean his SA was normal with 70% mobility but I just don’t know what to do! PLEASE help ♥️
