7 days delayed menstruation progesterone 13.16mmol / L consider a little low, not normal.
Under normal circumstances, menstruation has been delayed, then in the luteal phase or early pregnancy, under normal circumstances, the value of progesterone luteal phase is in 15.9-63.6mmol / L, and early pregnancy is generally in the 63.6-94.4mmol / L, so the value of 13.16mmol / L is on the low side.
At the same time, under normal circumstances, menstruation is delayed for no more than 7 days, if it is more than this time to consider not to rule out the possibility of living environment, luteal insufficiency or pregnancy and other factors.
If there is luteal insufficiency, then the progesterone will be low, which will also lead to menstruation; if during pregnancy, menstruation will not come, and at the same time, low progesterone, it may also lead to miscarriage or poor development of the embryo.
However, progesterone varies from person to person, and since progesterone is secreted by the pulse, the amount of progesterone in the blood varies greatly at different times of the day. If you have a low progesterone level and your period doesn’t come, it is recommended that you go to the hospital to find out the cause of the problem and get targeted treatment.
