Nothing is fitting

I’m 31 weeks pregnant. I’ve been big from the start you could say but now I just have a short while left I can’t get myself to get more clothes. My work maternity clothes don’t fit, my husband’s sweats are not comfortable anymore. I’m literally in his too big boxers so I have “at home underwear”. I’m at the point where I cry when I put on maternity clothes and they don’t cover my belly. Or pants that are too tight to go over my thighs and or too tight bellow my belly(maternity ones). My husband just bought me a xxl onesie and I was so excited. He was scared I would be upset about the size. But honestly I would be way more upset if it was a Xl and too small anyone else feel me? I can’t get up or down on the couch or bed without help now days
