Pain down there

Hiya, I am currently 37 weeks and 3 days pregnant and the past few days i have been having quite a bit of pain down there. When i go for a wee it has started to sting quite a bit and sometimes when i wipe there is tiny blood spots. I haven’t shaved recently so it isn’t a cut due to that so what else could this be? Anyone experience anything similar or know what this is? Xx
