Eh sayang, this sounds like something that really needs a doctor's attention, please go see one today or head to the clinic/A&E if the bleeding gets worse or you feel unwell. These symptoms together (vomiting, pain down there, and bleeding in urine) shouldn't be ignored, okay.
I know it's worrying, but a medical professional needs to check you properly to know what's happening, it could be many different things, and only they can say for sure. Take care of yourself, and don't delay getting checked out, alright? Sending you strength, mama.
