Momshie, this is really important, please talk to your OB about this na, especially at 32 weeks. They'll know exactly kung ilang times kailangan tested based sa iyong situation at health protocols. A few of us mums went through prenatal testing, at honestly ang doctors ang best to guide you through lahat ng kailangan para safe ang pregnancy mo at baby. Don't hesitate to ask your OB directly, they won't judge, promise!
