feeling very depressed today.

so my husband and I are ttc, but sex has been difficult lately. he works 60 hours a week and his job is very labor intensive so he is tired most of the time. he isn't ignoring me, but he's usually too tired for sex. and this week is my fertile window. I'm even ovulating today. so I've been trying every trick in the book to turn him on and nothing is working. I've tried flirting through texts throughout the day, sending naughty pictures, giving him a massage, dressing sexy, I mean I'm literally throwing myself at him and he just doesn't seem interested. and I know he's just tired but I can't help but feel unwanted. I've also been very self conscious about my weight and this isn't helping at all. I'm hurting and I don't know how to express that to him without getting angry. advice?
