I'm a 19 year old female currently sexually active. About 3 after protected intercourse I began noticing cloudy urine. I didn't think much of it because I had seen it before but it would always clear up either the next day or before the next time I went. This time was different because I started experiencing this strange urge to want to urinate even though I had already went a few minutes before. When I do go it's always a little bit of urine I never have a time where none comes out at all. After I urinate I feel a sort of tingling sensation from where it comes out to about the beginning of the pubic area. It feels like my bladder is completely empty but is still trying to force more out, as of right now it isn't painful just annoying especially at night because I have to get up 4-5 times a night to go use the washroom. Now, today, I noticed spots of something that looks like blood in the toilet but I'm not quite sure if it came from my vagina or where I urinate (Sorry, I'm not that familiar with some terms so bare with me) because I am supposed to be getting my period this month.
Any information would be greatly appreciated and hopefully everyone understands my explanation.
