Ovulation help

Hayle • 5 yr old daughter. 1 👼🏼 1-23-19. Ttc baby #2.

Need advice! I work 3pm-8am tomorrow, 8p-8a sat and Sunday. Hubs works 2 hrs away. I have an abundance of ewcm right now and some cramps. We bd Monday and Tuesday already but my opk is negative. I’m afraid i might get my peak tomorrow through Sunday and can’t bd because he won’t get home in time before I have to leave work. Do I make him come home tonight and In case I do get a positive opk through this weekend or try and wait it out? He’s in the oilfield
