Hi mama! Rice coffee should be okay since it's naturally caffeine-free, pero since you're 27 weeks, mas safe talaga na i-check muna with your OB just to be sure, bawat pregnancy is different, at may ibang ingredients pa sometimes na hindi mo alam. A few of us preggy moms actually dine on rice coffee kasi safe alternative siya sa regular coffee, pero definitely better to ask your doctor lang para peace of mind mo!
