when I was prego with my first my stomach was soft but my friend was hard. my doc told me I walked allot and didn't have dark stretch marks but she didn't walk and had real dark stretch marks and her stomach was super hard.
I'm almost 34 weeks and my mom says mine is still soft in her opinion. She says it's still going to get really hard. And it's still soft when I lay on my back. But I think I'm really small for 8 months pregnant so everyone is different:)
