Mama, I know that's scary to see! But please call your OB or go to the hospital ngayon na para ma-check, better safe than sorry at 37 weeks na. Brownish discharge can be normal sometimes, pero kailangan talaga ng doctor to rule out anything, lalo na may bleeding involved. Your baby's doing great sa ultrasound, which is good news, pero kailangan pa rin ng professional check ASAP. Thinking of you, sis!
