Yeast infection ?

Last 1 or 2 weeks ive had a slight itching after I go pee and a slight burning after I go pee which goes away but then I feel pressure and soreness at times in my pelvis and sometimes near my belly button and bloated at times. I missed my period which was suppsoed to be the beginning of September and I’m not sure what it is. I’ve never been sexually active whatsoever. I’ve been stressed a lot last month in August but my periods before this have been consistent so idk what’s going on can someone help? My diet hasnt been the healthiest lately so idk if that’s a factor tho but my weight hasn’t changed significantly lately so and I get discharge but it isn’t a weirdly colored discharge and there isn’t a significantly weird odor so
