Ate, please go see your OB or go to the emergency room right away, ha? Black and watery stools during pregnancy need to be checked immediately by a doctor, hindi dapat i-ignore yan. I know it's scary, pero important talaga na makita ng medical professional kung ano ang nangyayari, especially at 8 months ka na. A few of my mum friends had tummy issues during pregnancy, pero laging kailangan ng check-up para sigurado. Huwag mag-self-diagnose or mag-rely lang sa tips online, ang baby mo at ikaw, pareho pong importante. Go na to your OB or nearest hospital so they can properly assess you. Hoping it's nothing serious, but better safe than sorry, mare. Sending love!
