Period tomorrow. No signs..

Every month I have signs that my period is coming. About a week before my breasts get sore and tender. About 4 days before, I get bouts of heartburn. About 2 days before I struggle having a healthy solid poop. The day before I start, I cramp like hell. Well, my period is due tomorrow, and the only sign I have are sore breasts, they're just much more tender than usual. Instead of having any sort of poop, I cant poop for the past 2 days now. No cramping, no heart burn now. Has anyone else realised their menstrual symptoms, and noticed a month they didn't come??
