Hello everyone. I am 5 weeks 3 days and had my ultrasound today. Saw a gestational sac and yolk sac measuring perfectly for 5 weeks 3 days. I got my lab results and my hcg is good at 6,300 but my progesterone is 13. My OB put me on progesterone pills 200mg once a day. Anyone take this and it helped prevent a miscarriage?
