Maybe. I think it's more like she has always been a bit insecure about not meeting her family and friend's expectations of an "ideal conservative woman," having been fat-shamed on conservative television since she was 19, growing up "nerdy", and marrying later than most of her friends. I think this was part of her resentment towards Abby: Abby fits all the expectations to an almost scary degree (skinny, tall, pretty, polite, popular, married in college; the whole mormon dream).
Her father was dying when she had her wedding, so she couldn't have her "perfect" wedding. This pregnancy was supposed to be her moment to get to indulge in the same instagram-perfect moments as Abby and have a "normal" conservative family, but that's been ruined by COVID-19. So now she's breaking down over not being able to have these idealized experiences like crib shopping that she feels so entitled to, even though she literally could just go online and buy one like most people do nowadays.
