I need hope... is there any advice?

My husband returned home after 13 months of deployment. I positively surge for 12 hours as I've done since I started tracking 8 months ago but... My whole temperature changes this month only! Even fertility friend says my Temps are off and doesn't think i ovulated. So once again AF is here, and no pregnancy. I'm calling my OB tomorrow to see him but was really hoping we wouldn't need meds to get pregnant. I've never needed them with my other pregnancies. I was seeing a specialist right before my husband left & they think I was surging but not releasing the egg for some reason. I'm 41, is it age? I feel so bad for so many others struggling too. Even being in the same shoes, I can't seem to find any words of advice for myself. Now I have no interest in sexual intimacy too because I'm like what's the point. I just keep failing at getting pregnant... Just needed to vent 💔😢😭
