Hi mama! Abdominal pain at any point in pregnancy needs medical attention, please see your OB or go to the nearest clinic/emergency room right away, especially kasi umabot pa sa back and pelvic area. Hindi kami dapat mag-guess dito, kailangan talaga ng doctor to check what's happening. Fingers crossed it's nothing serious, pero better safe than sorry with pregnancy. Let us know how you're doing, okay? Sending you strength!
