TTC with wrong CM?

Ma

Is there any point in having babymaking sex on days when I don't have the egg white cervical mucus? I am really new to this and have three apps right now that are all predicting ovulation on different days... Fitbit says yesterday was the start of my fertile window, Glow says it starts tomorrow and Ovia says it starts Monday, lol. OPK is still negative but this is my first month trying to track ovulation so I have no idea when we need to start. Usually (while not TTC) I've assumed I was ovulating when breast tenderness and egg white CM showed up.

TL;DR, I MIGHT be in the fertile window but have bad CM at the moment... Should I even try? Husband is exhausted/stressed from work right now so I don't want to harass him unnecessarily.
