Mommy, please go to your OB or the nearest hospital right away, these signs need to be checked immediately, hindi ito dapat maghintay. Leaking fluid and a hard belly could mean something urgent, at kailangan mo ng proper exam para malaman kung okay ang baby mo. One of my mum friends had something similar at nag-rush siya, glad she did kasi priority talaga ang safety ninyo dalawa. Don't worry, ang doctors dito ay very helpful, especially sa first-timers. Keep us updated, okay? Thinking of you.
