Anyone else find themselves so angry?

My fiance works in the oilfield and is home one week and gone a week looking at my months to come on glue I might as well give up because I started trying last month and this month I got 5 days of flashing smiley and then my peek smiley last night and my man won't be home until tomorrow evening and last time we had sex was Tuesday night before he left. I just can't help but feel like giving up cause looking at my calender my ovulation dates are all gonna be while he's gone. And I'm always regular within a 3 day period. So I guess I'll just give up because with his job I'm just setting myself up for heartbreak.. I wanted to conceive this month and have an August baby 😢
