when does your stomach start to "harden"?

It might be my over-active imagination again, but I think the lower part of my stomach, nearer to my pelvis, has started to feel firmer today. I've had a bloated stomach for the last few weeks, but it was still spongy till now. I had a few aches and pains in my stomach yesterday (not cramps, more like growing twinges). I know the pregnant belly is "hard" later on, but does anyone know when it starts to get firmer?

for me it was around week 11

I thought it was around 12 weeks when your uterus comes out from behind your pelvis But don't quote me on it!

Mine only feels hard after a big meal! but I'm only about 9/10 weeks so I suppose it's still way too early for it to go completely hard. I think it will be harder around week 11 or 12
