Has anyone ever has a ton if pelvic pain and pressure before their period was due? I am definitely not pregnant and my period is due tomorrow. The past few days I have had soooo much pelvic pressure and a heavy/ full feeling in my uterus. Going up the staies and certain movements are really uncomfortable because it feels so heavy! I am so uncomfortable! Could this be related to my cycle? I have been debating about whether I should wait a bir or go to the doctor. I have just never had symptoms like this before my period.
