No symptoms

According to glow my period is suppose to come today. I have no signs or symptoms of it coming. Normally I cramp. My period is like clockwork. Had some brown spotting yesterday morning but nothing since. No sore boobs, no back pain. My breasts appear to be a lot larger but not painful. 5-6 dpo I had cramping in the Evening as if I was going to start any second but they eventually went away.... Feedback anyone?
