Possibility I have a UTI?

Crystal
My boyfriend and I spent the weekend together and had sex a fair amount. The morning after he went home I had horrible stomach pains and when I went to the bathroom it hurt to pee and I bled slightly. I assumed that something tore. However, it has been a couple days and I've been peeing frequently and it hurts to a degree which makes me believe I have an UTI. Though when I pee it's not a weak stream. Is there a way to test at home if I have an UTI? Does Planned Parenthood treat UTIs? Advice would be appreciated.
