Progesterone

I got blood drawn to check to see if i ovulated or not this cycle for iui and my doc said i did and my result was 10.84 is that a good number or ? She put me on progesterone 200mg to take vaginally every night and im just curious is that a good thing should i be worrying that the iui didnt work? Has anyone gotten pregnant with progesterone of 10 and up?
