need encouragement for BFP

We are trying to get pregnant for a Christmas BFP but my fiancé will be gone during my ovulation. I'm crushed. I don't want to wait another month. I want this to be our month. He will be back the last 2 days of the ovulation period. But I'm still nervous it won't be enough. I can't post this anywhere else. So I'm venting here. any stories about how you got pregnant even when before/past  ovulation ? 
Thanks ladies ❤️
