Wat time of the menstrual cycle is it best to take the 24 hour urine cortisol test? would taking it on the 2nd day of bleeding pose any problems?

In brief: Yes

Any 24 hr urine collection should be done when you are not having menstrual bleeding, otherwise the blood in the urine will give incorrect results.
