Uy, at 39+ weeks ka na, definitely best to call your OB or go to the hospital right away para ma-check agad, hindi worth waiting on this one, mama! Pink or brown discharge near your due date can mean different things, at need mo ng doctor to be sure if it's labor signs or something else.
Wag mag-alala lang, pero please go now para peace of mind mo at ng baby. Sending you strength, you're almost there na!
