I actually can't remember - but I think that it did occur during a couple of early flushes. I have been perimenopausal, so I was glad to be menstruating again and found it to be a good sign in my situation. The liver produces and regulates many hormones so -- no wonder!

Hopefully yours settles down!

The liver flushed actually helped regulate my periods as before i started i was havig one every 2 months, now i have one once a month.
The first 2 flushes my periods were pretty painful, but the last period i hardly had any pain at all :)

Hi! I have experienced something similar. I used to have excruciating cramps each month till I did my first Master-Cleanse and LF. I passed many stones, and now my cramps are very light and easy to manage. I'm wondering if your cramping will lessen with the more LC's you do? Just to let you know something that helped me while my cramps were bad...my doctor suggested taking a dropperful of cramp bark every 5 minutes till the cramping subsided (even prescription painkillers didn't help). Usually it didn't take more than 3 doses for me, and it worked like a charm. Hope things get better!
