Since I started cleansing in November (2 MC's, 4 liver flushes, parasite cleansing and about 50 days of B&P's) I have had 'invisible' periods! It's quite crazy. They just sneak up on me out of nowhere...I don't get tired, no headache the night before and no cramping or even that heavy, hot, abdominal feeling now! It's quite unbelievable!
