Uy mama, yan kailangan talaga i-check ng doctor mo right away, lalo na may white discharge at approaching na ang due date mo. Hindi okay na mag-assume dito kaya please call your OB or go to the hospital na para peace of mind mo at baby mo. One of my mum friends had something similar before, nag-panic din siya pero good thing she went in agad, palaging mas better safe than sorry tayo especially pag malapit na. Fingers crossed for you, but please don't wait on this one, ha!
