Hi mamsh! Congrats sa 27 weeks! Because you have GDM, please check with your OB first before trying anything new, even natural drinks, para sure na safe at hindi makaka-affect sa blood sugar management mo. GDM is really something we need to handle carefully with our doctors, hindi trial and error lang. A few of us moms with GDM swear by what our doctors prescribed, kaya really best to ask yours kung ano talaga ang okay for you. Sending you strength, mama!
