Lisa -

RLT you can start at anytime really, preferably in the second tri. So you are fine to drink it now. 3 cups a day, and then around 35 plus weeks go to 5 cups if you can stomach it. Or go to a naturopath and get a liquid version and take it once or twice per day.

The EPO start orally around 34-35 weeks, just 2. And vaginally 37 weeks - 2 capsules in the night before bed, 38+ weeks can up it to 3 or 4.
Remember to wear a pad. What goes in, will come back out.
