Progesterone urine testing 4, 5, and 6 days post ovulation) what does this mean?
When only one line appears that means supposedly that progesterone levels are greater than 5 in urine which is equivalent to about 10 in blood. Notice how 5 days post ovulation the line is the lightest and then gets darker on 6 days post ovulation. Does this mean I am not pregnant for sure?
