Bladder issues

I’m so nervous. I’d been having some pressure and a little pain in my pelvic area and decided to address with my OB-GYN first although they didn’t find any issues after an exam and transvaginal ultrasound. Since I was also feeling the urge to pee more often and didn’t feel my bladder was emptying I was referred to a urologist. I am a 34 year old female that has had two c-sections in the past. I do not have a UTI but at the initial appt with the urologist they noticed I retained 88 cc’s of urine after I peed in a cup. However, after the appointment I received a call that there was blood in my urine (nothing visible to the eye) and I have to get a CT Scan. I also have what I can only describe as some kind of lump at the front of my vagina. It’s not painful at all and the OB dismissed it and said I may be feeling my uterus. It was never that way before. I’m really concerned it’s something serious as I don’t think I should be having bladder issues at my age :-(
