Raspberry Leaf Tea, Evening Primrose Oil, and Dates

Da
I'm 36 weeks 1 day...I just started ALL of them today.  I'm just not completely sure how often I need to take each one.  So far, I've had an 8 oz cup of Raspberry Leaf Tea, 1 capsule (taken by mouth) of Evening Primrose Oil, and just a couple dates.  Any advice?
