Mama, chest pain or anything involving your heart during pregnancy needs to be checked by your doctor or go to the hospital right away, hindi dapat ma-delay yan, okay? Please don't wait on this one, lalo na may ECG findings involved. I can't explain what that means or what it means for you, pero alam ko na importante sya at kailangan ng doctor to look at it properly, so please get yourself checked ASAP. Wishing you and baby all the best.
