Progesterone help

I’m on cycle day 21 and I got my blood drawn today for progesterone level, I take clomid cycles day 5-9. This is my second month on it, last month my level was a 6.4 and my doctor said it was low. I know you all aren’t doctors but maybe you could help me a little bit. I have PCOS and I just want to know if you think I may be out this month.
