Mama, for anything ingestible when you're that far along, especially at 37 weeks, mas better talaga na tanungin mo muna ang OB mo, kasi alam niya best ang exact situation mo. I get it, gusto mo ng safe remedies, pero ginger-based drinks like salabat are one ng those gray areas na depends on how much, how often, at kung may underlying conditions ka, kaya better safe na safe and check with your doctor first, ha? They'll give you the clearest answer for your pregnancy.
