Is it possible?

Brooke • Mommy to Nolan - 12/16, Due with #2 🎀 11/6/18.
So my last two cycles have been 32 and 33 days.  Based on glow tracker my best days to conceive are next week.  AF started 12/30 and ended 1/3.  I've been taking opks this week and all negative. 
My husband leaves tomorrow for a 3 week work trip.  We obviously are going to try tonight and tomorrow but I'm so worried we are missing out peak time.  
So bummed - any advice or encouragement appreciated.  Really wanted this month to be the month.
