Mama, this is actually a question na best to fully discuss with your OB since they know your full health picture, they wouldn't recommend it kung hindi safe para sa iyo at sa baby mo, kaya trust their judgment! A few of us moms din nag-booster while pregnant dahil sa OB recommendation, at nandito lang kami ngayon, but every pregnancy is different, so really ang best person to talk through any worries mo is your doctor mismo, they can explain kung bakit kailangan at what to expect. You're doing great na nag-follow up pa!
