What is happening??

Just this past hour, my lower part of my vagina started hurting and I felt the urgency to urinate. When I pee, it feels pressure when I push. There are also very small small bubbles in the toilet that are clear and my urine is clear. There are small drops of blood, even though I’m 9 days away from my period. I started birth control in March, if that effects it. This is what came out when I was urinating, not too big, but it’s not occurred before, to me. I am sitting at the moment and have the urge just to go to the bathroom and stay there. What is your opinion on what it is???
