Progestrone Level

This is my first round on Clomid. I took 100mg days 3-7. I ovulated CD18. Went in for follicle scan and had one on each side. We did IUI that same day. I did my one week post IUI progestrone level yesterday and it was 16.4. Does anyone know if this is good or bad? Doctors office says it means I ovulated but does it seem low?
