I never truly got symptoms when my monthly would start. A lot of the time it would just pop and surprise me. I went on birth control for a while to monitor when I would start. Then went off of it and stayed off for a few years. Since having my daughter I have had cramps that leave me feeling sick to my stomach. But not each time. Am I the only one who gets surprised by their monthly? I use a tracker but it still pops up without warning or days later than it should.
