Am i Pregnant?

So ill get right to the point. Ive been a moody bitch the last couples of days, ive been so tired like literally domt wanna get outta bed tired, cramping like period pain but not ( i know that makes no sense but excuse me period poos kinda feeling) and pain in my lower back. Its honestly like im on my period and but im not and shouldnt for another 11 days or so. My nipples are sensitive and my boobs are so tender. i also have these lumps that are benign (i cant spell there name lol) but that enlarge and hurt with hormones so say im getting my period theyll hurt and get bigger. but this isnt when it normal happens and its so odd. Any Suggestions? or ideas? please help
