Progesterone?!

Krystin
Ok help. lol I went to the doctor yesterday to get my blood drawn to officially know if I am pregnant. My period is 30 days late. My last one was April 20th. I've had 3 at home positive tests since then! 
The blood takes 48 hours till I'll know and he said I have to come back in on Monday but my medical app that all my results go to , notified me this morning that my progesterone came back at 16.6! 
SO does this mean I am pregnant ? And I'm pretty sure I am so if I am. Is this too low of a number ? I should be around 7/8 weeks in my
Pregnancy.
