5, and my hcg more than doubled. My OB prescribed
Prometrium 200mg, saying he wanted the progesterone level >20. My concern is his refusal to check my progesterone level after taking the Prometrium. He says the results would not matter, as he would not prescribe any additional progesterone, saying the body "can only absorb so much."
I have a friend whose OB tested her progesterone, and prescribed 200mg Prometrium for a level of 8.
