Quick question..

Every time I sit on the toilet & the baby moves warm liquid comes out. ( I know we are all thinking its pee) but it comes out EVERY single time he moves, I've been feeling tons of pressure today, & not to mention I was just in the hospital for preterm labor. I'm only 34 weeks now... So what should I do? I know I should smell it but every time I do it don't smell like anything. It's just plain clear liquid.
