I have a question concerning my lady parts and there recent "actions.":)?

Hey there. so im 22yrs old, healthy, active, good sleeping habits and eating habits, regular period cycle of 31 days. heres whats going on...i got my period july 30th. Last week wednesday i started cramping. not bad bad cramps just slightly uncomfy. my breasts also got extremely sore. I thought no big deal, so im pmsing a little earlier. well starting this last saturday ive had cramps coming and going, none requiring any pain reliever, but sometimes waking me up for a bit,and always low just where i usually get cramps. my boobs also stayed very tender And my back omg my lower back about took me out.of my whole saturday! I noticed yesterday i pee'd probably.somewhere close to 30 times! Thays.the only day tho.This has continued on and it is now the following wednesday afternoon from when this started last wednesday and still crampin but now bloated, breats are only.tingly today and sometimes for a short time (30secs-1min) i get a really bad sharp pain in my right side. it really surprises me!! Almost took my breath the first time it happened. i've also been moody, mostly crying...and snapping at my confused bf. WHAT could this be?? My period still isnt due until friday but im...uncomfortable:( im wondering if something could be wrong with me or could i be pregnant?? i think im losing my mind or something. i feel like a nut, i couldnt be pregnant! :/thanks so much for reading, sorry so long amd sorry for the typos. new phone amd the keyboarf gets ahead of me sometimes! Any advice would be.wonderful!!!
