Uy mama, sending you the biggest hug right now. Please keep listening closely to your OB, they know your situation best, and whether bedrest or admission is right, they'll guide you. This is scary, I know, but you're doing everything you can para sa baby mo, and that's what matters.
A few of us mums went through worried pregnancies din, and what got us through was just taking it one day at a time, rest when you can, stay hydrated, and don't hesitate to call your doctor anytime something feels off. You're not alone in this, ha. We're all rooting for you and baby. Laban, mommy, you've got this, at nandito kami para sa inyo always.
