Ate, please see your OB right away or go to the hospital if you can't reach them, better safe than sorry, especially this close to your due date! Yellowish discharge can mean different things, at may iba't ibang reasons, so kailangan talaga i-check ng doctor mo personally para malaman kung ano talaga and kung okay lang baby mo. I know first-time moms kami ay nag-aalala sa lahat (guilty here din!), pero ito talaga one of those things na dapat professional ang tumingin. Call your clinic now or go to L&D, okay? Praying for you!
