Am i worryin over nothing???

so last night i thought i was ovulating & i keep getting white discharge too.
im supposed to get my period in a week but ive been having to pee alot lately today. Since this morning ive been experiencing my vagina being itchy and awkward feeling, but NO burning while i pee, so i strongly think i have a uti again. Do you think im just gettimg my period & have a uti or pregnant??? 
I always get super scared and worried so please help
