Fiancé out of town for work EVERY time I ovulate!!

Hi ladies! Just wanted to vent my frustrations and see if anyone’s in the same boat. My fiancé and have been trying for #2 for a couple months and I am so frustrated! His job makes him go out of state for a few nights every other week or so and all his trips for the past couple months (and the next few months!) line up with my expected fertile window. How the heck am I supposed to get pregnant now?!? Our first baby was an accident and I took for granted how nice and easy that was! Now I’m just hopeful for a miracle lol 😂
