Hi I'm Dr Sharon
I have gone through your query and understand your concerns.
A blunt trauma
to the perineal region,like falling from a horse can occasionally result in rupture of urethra
(which is the narrow tube through which urine comes out of the bladder) Though this is rare in females,there is chance since you have pain during peeing and bleeding from vagina.
So my advice is to approach your O&G specialist ASAP without waiting till tomorrow.
Wishing you good health.
