Every cycle is so disheartening

Girls, I’m just here to get it off my chest before I have a meltdown again. I’ve been trying since August. I’m 34 and 6 months. Every month I really think I’ve done enough, but it’s never enough and the cycle starts again. Can anyone recommend a lifestyle we should absolutely be doing to utilise every chance. Temps, testing, BD - when to start, how to continue etc. I can feel it hurting every single time I get a negative. 😓 Xxx
