Ay nak, I totally understand your worry, having two doctors prescribe different things is confusing talaga! But please don't take both at the same time without checking first, this is really important for your health and baby's safety.
Call your hematologist's clinic directly tomorrow or visit in person para ma-clarify kung pwede ba i-combine, or which one priority. Some clinics have emergencies lines din, or try asking for an urgent callback. Your OB secretary might also have after-hours emergency contact. I know hassle, pero ito yung time na kailangan mo talagang mag-check in person or by phone, hindi dapat maghintay lang ng reply sa text. A few of us moms na nag-take ng multiple prescriptions learned the hard way na kailangan talaga ng doctor's go-ahead para ma-sure walang overdose. Alagaan mo yan mismo, okay? You and baby's safety muna.
