Hi!
We likethe number to be above 15, which yours certainly is!  I expect that your RE is going to continue progesterone supplementation through about 12 weeks.  That is typical.
At about 7 weeks the placenta kicks in and takes over progesterone production from the corpus luteum cyst which then regresses.  Most of the time the placenta is doing a great job by 12 weeks so there is no need for any more injections.
When I went through IVF, they didn't even check progesterone levels.  So, I think that as long as they are over 15 the REs are happy.  No need to worry about too high a level, although you can certainly ask your RE if you can reduce your dose.
Good luck! Congratulations!
