TTC ovu day

My ovulation day is Dec 1st my husband is leaving for drill Thursday. Like tell me straight up what my chances are of conceiving if he’s gone the main fetching day I’m ovulating. Obviously we are doing the deed every night and I’m gonna make sure it gets done on Thursday before he leaves. But like 😩 I’m gonna be so sad if I don’t get a sticky one this month because of him leaving. Reassure me. TTC for our 3rd baby btw. This is the first time I’ve ever tracked my BBT and ovulation.
