Utrogestan 10 days per month. One pack with 30 capsules cost US$ 8.10 and last for 3 months. When I don't take P4 the P4 blood test shows about 0.4 ng/dl and during the 10 days with P4 it shows about 2.5 ng/dl.

No one's ever prescribed Progesterone for me!

but it still comes up in my blood test results..
