Changes in Menstrual Cycle in Ladies Only Posted February 7, 2014 We did a Whole30 in January and I had a pretty miserable period from the fourth to the ninth. I started my period again on the 30th (weird for me as I usually have 30 day cycles). Then we took a few days off, I ate way too much sugar, and so we started another Whole30 on the third. I'm still on my freaking period. Day nine. My long cycles are six days. This is getting crazy. I'm hoping if I just keep eating Whole30 compliant it will all even out, but this is miserable. I get cramps, exhaustion, and really awful depression before and during menstruation, so it's been a rough month.
