pregnant after ectopic

Casey
Hi there. I am finally approximately 4 weeks along after having an ectopic 2 years ago. My hcg is looking great. Went from 173 to 403 in less than 48 hours. However, my progesterone was 19.5 and then dropped to 18.6. Should I be concerned? Should I ask for progesterone supplements? She hasn't called me back yet and I'm panicking!! To miscarry after ttc for 2 years would be devastating!!
