Progesterone

So I switched Drs. My new Dr. made me feel so comfortable and secure in her care😍 I’ve had 2 losses in the last 6 months and am now pregnant at almost 9 weeks. Baby measures younger. I’ve had bleeding and pelvic pain so she ordered me progesterone and I don’t know much about it but I’m so glad my concerns of another loss have been taken seriously. She ordered the test test right away and I’m so grateful. Any other moms out there have success with it?
