I do believe my weight gain is because i started my TOTM this morning 3 days early. I have read a few posts on here about peoples TOTM's being up the left whilst on CD and now its happened to me. (im on the pill and normally can put it down to exact time im that regular) but hay ho, at least i know why now
starting weight 13,10; 1st WI -8lbs
Answer Cambridge Weight Plan: Consumer FAQs: Medical Queries: Does the Cambridge Weight Plan affect the menstrual cycle?
