Is having sex before ovulation really better than during?

Ryan • mommy to niko

Interesting convo i had with a friend today about her journey as well as mine. She had a sono and was told that she is close to ovulation (obviously they can not see the exact moment of). But she mentioned to my friend she should have had sex the day before. That the sperm has to already be up there waiting for the egg.

If thats the case then tracking opks is just a waste of time because u still may miss it

Any validity to this?
