Red Raspberry leaf tea


So.... I heard that you are only supposed to drink at the most 3 cups of the tead a day... And ive been drinking six.... And only just heard about the three rule... Is this true and what could happen to my baby? Will it put me into labor? I am 39 weeks but still... Could it hurt baby? I usually drink it out of a 50.72 fl oz. Bottle, so it is usually.drank in the same ish sitting... Or is it probably just fine?
