Hey mama, brown discharge close to your due date can be normal, often it's just the mucus plug or old blood, but honestly, better safe than sorry kaya seryoso, contact your OB agad to get checked, especially since you're almost ready to pop na! One of my mum friends had the same thing at 38 weeks and it turned out to be nothing, pero the doctor still wanted to see her just to be sure, so don't worry if they ask you to come in. Ingat ka always, first-time moms deserve that peace of mind.
