Ay, wala akong personal experience with raspberry leaf tea during pregnancy kasi hindi ako gumamit nito, pero honestly sis, better ask your OB about that one, lalo na since 2nd trimester ka pa lang, importante na sigurado tayo sa timing at safety ng anything we take. A few of us mums have asked our doctors about it and they usually prefer to give the go-ahead based on your specific health situation, kaya don't skip that consultation!
