Hay nako, first time mom ka talaga! Please check with your OB about pineapple juice, it's really a question para sa doctor mo since you're at 34 weeks na, para sure lang na safe at okay para sa iyo at baby mo. Every pregnancy is different, kaya mas better kung makakuha ka ng personalized advice from someone who knows your health history, di ba? Marami sa mum friends ko ang nag-ask din ng ganitong tanong, kaya you're not alone dito! Let me know what your doctor says, okay?
