Mymonthlycycles.com says that I was supposed to start 10/22. Pink pad Pro says that I was supposed to start 10/23. Glow says that I am to start on 10/29, but I have 31 day cycle and the 29th puts me.way past that. I have noticed that all of these days are within a week. It is the 25th and I still haven't started yet, but I have been feeling overly emotional, severely clumsy, nauseous as can been, and I have vomited twice. What do you think?
