Mama, please call your OB or go to the hospital right now to get checked, with pain like that at 37 weeks, kailangan talaga ng doctor to make sure everything is okay, especially since it's different from your first pregnancy.
Yan na ang safest move, hindi lang pag-antay sa bahay. Sige na, alam mo na ang feeling ng labor from your first, pero iba-iba talaga ang bawat pregnancy, kaya let the doctor confirm kung ano na talaga. Sending you strength, mama! Keep us updated pag okay ka na!
