Based sa timeline mo, you need to pay for February, March, April, May, June, and July to keep your coverage active until your August delivery, that's 6 more months of premiums kailangan mo pa. Since consistent ka naman sa payments, mas okay na bayaran mo na lahat ngayon or spread it out monthly para sure ka na covered ka during labor, kasi ang hassle if may emergency ka walang active Philhealth! Best to verify din sa nearest Philhealth office or check your member portal para makita exactly kung gaano kalayo ang coverage mo, para peace of mind lang talaga.
