Progesterone supplements or no?

Lacie

Last week my progesterone level was measuring 7.21 for 6 weeks pregnant. My doctor is not concerned in the slightest and says anything over 5 "ought to be ok". She did say however, if I would like progesterone she will give me a prescription for a vaginal supplement. She followed that up by saying she believes my levels "ought to be ok" again and that progesterone is not routinely given anymore. She also said we can wait for the results of my ultrasound this week and go from there (I have a repeat ultrasound on Saturday as they were only able to see gestational sac and yolk sac last week- the gestational sac measured 6w0d so the radiologist and tech both said it was probably just too early).

I guess my question is, do I ask for the progesterone, even though she says it "ought to be ok" or do I follow the advise of my MD and hope that her saying everything should be okay will work out? I have had 2 miscarriages and really don't want to add a third.
