Injectable Progesterone vs RDT - What Works Best?

Why do OBGN's always recommend the injectable progesterone rather than miscarriages during pregnancy? It's weird cuz they don't use it any other time yet they admit it's real and works and so they don't want to give injectable for hot flashes though. They don't know about RDTs or capsules or Prometrium which has only been a

prescription for 55 years, right? About 55 years it's been out. How do you miss that? How'd they miss that in medical school and residency? What's the best way to get progesterone into your system? like oh bar none the RD2 but that's a prescription that's a little tr I don't know there's

other options that can work for 95% of people of women out there so you don't have to go to that expense or trouble
