Uy mama, RhoGAM is really important kaya you need to check with your OB or the hospital right away, hindi ito something to delay, ha! Call your doctor or go to the nearest maternity hospital in Cebu (like Chong Hua, Visayas, or the public hospital) and ask them directly kung available, kasi they'll know exactly where to source it quickly if kailangan mo na talaga. Sending you love, alam ko stressful ito!
