Ovulation dip? Maybe?

I had EWCM for 3 days straight, no positive OPK until today. App said negative but looked positive to me. I had what looks like an ovulation dip this morning? I know I need to have 3 high temps to confirm, but possibly? We had sex last night and were going to skip today since we’re doing every other day this cycle. Not sure if we should do it tonight or skip until tomorrow?
