Mama, I'm a bit concerned with what you're describing, severe stomach pain plus watery stool together can be something na kailangan tingnan ng doctor, lalo na ngayon na pregnant ka. Please go to your OB or emergency room today para ma-check, hindi kami makakapagsabi ng sure kung normal lang yan o hindi without a proper exam. Huwag mag-atubili, okay? Ito para sa peace of mind mo at ng baby mo. Keep us posted, sending love!
