@eandc2006 thank you for the post - I'm getting ready to start IP and am garnering lots of information about the diet. I'm actually interested in learning more about menstrual cycles and IP. Since there is rapid weight loss on IP, I would assume that cycles are somewhat irregular (??)
Random question, but I wonder if the effectiveness of hormonal contraceptives is altered somewhat on IP. DH and I are not ready for a surprise baby at this point
Anyway I'm glad you gave this heads up so that I can have some idea of what is going if I have spotting/break-thru bleeding.
