Mama, alam ko na nakakapag-alala yan pero okay lang, your doctor is on top of it na with your ultrasounds and check-ups, at ang baby's heartbeat is strong pa rin. A few of us mums in our circle experienced on-and-off bleeding in the third trimester din, at honestly ang best thing talaga is to stick to bed rest like you're doing and just trust your OB, they know what's causing it at bakit kailangan ng utrogestan at isoxsuprine mo. Ang lagi naming sinasabi sa isa't isa, "ang important ay ang baby's okay at ang cervix ay closed pa," which is your case! Rest up, monitor any sudden changes, at ang Saturday check-up mo will give you more answers. You're doing great, mama, I know it's frustrating pero you're taking care of yourself and baby already.
