Mama, I know it's scary, pero at 38 weeks, kailangan mo talaga makita ng doctor agad, hindi ito something to wait on, okay? Light brown discharge can mean different things at this stage, and only your OB can check properly if everything's fine. Please call your doctor or go to the hospital now para ma-check. A few of us moms have been there, and ang peace of mind from getting checked is worth it talaga. Sending you good thoughts, go na!
