Victoria
5 days late. Breasts have been sore over a week. Been having cramps like if im about to start. Had some white mucus looking thing around the day i was supposed to start my period.i have been pooping so much lately. And its either a little poop or just regular. My boobs are just super sensitive. Super sensitive. Have never experienced something like this. Period is never late.
