Frustrated!!!😠😤😣😦😢

This is the 3rd cycle me and my SO have been ttc now. Since having our first child (7years ago, not trying) my sex drive went straight down hill. Im talking having sex once a month. Now we are ttc i feel like we have switched roles and im the one with the high sex drive and he is always too tired. My SO has been asking when im fertile this month which makes me think hes really into it and is actually trying. But tonight according to glow im most fertile and hes snoring away! Tomorrow night, im busy then the next night he will be out drinking and no doubt the night after he will be too hungover and then my fertile window will be over! (And yes we do only have sex at night as its a bit hard with a 7year old in the house) ....

Anyway, im just wondering if anyone else has gone through the same thing? Or if anyone has some advice for me? Because i dont want anything more than another baby and im sick of hearing itl happen when it happens 😢
