Okay please help me lol

I'm trying to stay on a more healthier diet. I go on a master cleanse about once a year to detox my body. I'm trying to figure out if I can continue the week of cleansing if I just started my period on the 3rd day of my cleanse. I'm already very tired as it is and I'm a little scared to continue because I don't want to put to much stress on my body. Should I just call it off and wait for my period to end? Or can I continue
