TTC while being in a long distance relationship

Soooo I've been TTC for over a year now & no luck 😔 About 6 months ago I had to move for work so now I'm in a long distance relationship, I don't want to give up but I feel it may be too late . We both want a baby however the Kong distance puts a strain on our sex life , I only get to go home once a month & still no luck. Every time I return my period comes a week late so I think yay & then boom 5 days of Aunt Flow raining on my parade. Definitely need advice 😩
