Can understand your concern. Used to be quite proud of slim and fit figure, with tiny tummy but then pregnancy requires us to gain weight for the baby and you lose that figure and tiny belly very quickly and it's very demoralising. I'm also on the petite side and only 22 weeks now but my belly is already so big and tight that I have no more belly button. 😭
But for me, I'm lucky to have a very supporting husband who still keeps complimenting me about my body despite my ballooning size and even helps me research on post pregnancy recovery in the background.
Seems like there's post natal massages and wraps which can help you quickly reduce belly wind and shrink your belly right after birth, and there are also oils which help you to reduce stretch marks during pregnancy. Nowadays also have those tummy shrinking therapies for post birth which looks like it costs a bomb but can prolly consider if you have the finances. Can research to see if these helps you.
But I think the most important is to talk to your significant other, your besties or parents etc. Feel that it's difficult to go through pregnancy without a lot of psychological support, and having someone to talk to helps alot in the difficult journey. 🙂
