Progesterone Rise

Question! My progesterone is literally always a 10 or a little over a 10 seven days after ovulation. I really expected my dr to message me today and tell me today’s test was no exception and that again I was coming in at a 10 and should start my support. Only today she said I came in at a 15 ... on my own. Could this be a pregnancy sign? I’ve never came in that high on my own.
