It may be due to bleeding from a cyst. If you lie down, check your pulse. If it rises about 15 points after you stand, you may have internal bleeding and should consider getting seen. I do not think this indicates normal ovulation. There is likely some progesterone production by the cells in the ovary, but not a normal ovulation.
Many labs use different values, but that is quite low.
I always have low progesterone levels with good flow and temperature spikes. Mperloe Values in that range can also be seen in the follicular phase when we are performing ovulation induction. On clomid 7 months. Mperloe SK you are seeing an amateur. 3-4 months is more than enough.
