Is it safe to do a Liver Flush while having a period? I've done 5 flushes so far. Two flushes were at the end (so I thought) of my period. Both times I experienced a sudden heavy flow for a day after the liver flush. Could it be that the flush got things opened up and moving through? I'd like to do a flush again this week, since I'm having more gallbladder pain again, but don't know if I should during my period. My last flush was more than 3 weeks ago.
