My doctor did my blood work at 16 dpo and my progesterone level came back 18.3 . Then i went her office for ultrasound at 7 to 8 weeks . Everything was fine baby measured 7 weeks with 148 heart rate and she also did my blood work and my progesterone came back 18.3 again . That means my body didn’t produce any progesterone. My doctor put me on 200 mg progesterone supplement for full first trimester. I’m scared because i had one miscarriage last year january. Is anyone had samething and had successfull pregnancy. Please help me out .
