Uy mama, I understand ang stress mo talaga, lalo na sa fourth baby! But please please talk to your OB about this, they need to monitor you closely these last weeks kasi ito talaga ay medical decision na kailangan ng proper ultrasound at check-ups, hindi lang kami mommies ang makakasagot dito. A few of us sa group have had similar situations, and ang difference talaga ay depende sa kung saan exactly ang placenta at how it progresses, some moms did deliver vaginally pa rin, pero kailangan talaga ng doctor's guidance. Go see your OB soon if you haven't this week, okay? Rooting for you!
