Progesterone level of 15

This month I started taking 50mg Clomid and did an HCG trigger shot. I had my 7dpo today and the levels came back at 15 for progesterone. They told me my levels were all normal. From what I've been reading, levels are supposed to be over 15 for a medicated cycle. Does that mean I had a very weak ovulation and little chance of pregnancy?  I just need to stop reading the Internet. Always makes me feel worse.
