Thinking it's not our month

We tried to do the deed this week but didn't have much time. We did it a few times but I've been waking up at 3am for work and not getting home until 9pm, husband was on call and out almost every night from the time I got home until I left for work😩 as much as I want this, I'm overall calm about it not being our month (most likely). It sucks but maybe instead of a Christmas baby we will have a positive test in January to start out the year...
