Is your progesterone the same high level when you are possibly pregnant or period coming?

Can't say: Progesterone levels in blood during the luteal phase (two weeks after ovulation and/or conception) vary too widely to distinguish pregnancy from normal ovulation. Luteal Progesterone levels are unreliable even for the so-called luteal-phase defect, they really only say you did-or-didn't ovulate.
