Confidence in the third trimester

Looking for tips on how to stay positive and maintain some semblance of confidence as the end gets closer. I am on a little bit of a vacation with my hubs and while when I look in the mirror I feel like I can look cute when I try, every picture of us from this trip I look awful. It doesn’t help that we have been intimate approximately once in the last two plus months. He says he just doesn’t feel horny, I say that’s clearly directly tied to my current appearance. We overheard a couple in another room getting busy earlier and it was painfully uncomfortable. I’m usually a decently confident person but I just feel so unattractive and sad. I’m only 30w so I have so much further to go.
