Thanks for the query.
You didn't mention anything about your menstrual cycle.
This pain could be part of premenstrual syndrome
or ovulatory pain depending on the period of the cycle.
In both these conditions spotting can be seen.
Excessive exhaustion during jogging can lead to muscle cramping, so better to take enough water before and after running.
If the thing repeats better to consult gynecologist and examined once to find out the cause and take treatment accordingly.
