Hi mama! Buko juice is generally okay during pregnancy kaya pwede mo syang i-enjoy, pero since you're in your first trimester, mas safe pa rin na itanong sa OB mo kung okay ang araw-araw talaga, basta fresh at from a trusted vendor para sure na clean. A few of us moms drank it regularly throughout pregnancy kaya hindi unusual, pero better safe than sorry lalo na ngayon pa lang kayo sa early weeks, diba?
