Hi mama! Congrats sa pregnancy mo! At 16 weeks, super important talaga ang vitamins, a few of us here took prenatal vitamins throughout, kaya if your OB prescribed something specific para sa iyo, suportado talaga siya ng lahat. What vitamins exactly ang recommended ng doctor mo, or may specific concerns ka ba? Better to confirm din with your OB kung okay sa'yo lahat ng ingredients, especially since you're first time, they know your health history best at kailangan lang of peace of mind for you and baby. Excited for your journey mama, you've got this!
