TMI !!

I reeeally need some help Ive been having pink discharge and for the past day I've been feeling this tingling sensation like sofa inside of me or something. I do tend to hold my pee while I'm at work because I have a phobia of public restrooms. For the past week I've been craving sugar and soda and chocolate and usually I eat healthy and I don't drink soda anymore. I'm not supposed to have my period for another month just about. Do I have a bladder infection from holding my pee or am I pregnant? HELP ! (I just went pee and seen this in the toilet)
