33 yr old female virgin. 160 lbs. Constant need to urinate beginning in 2015 or so. Getting up at least once, sometimes twice a night. Going at least 15-20 times a day. Feel like bladder is now holding less. I could feel an urgent need and only release 1/2-1/4 cup. Went to two urologist April/ Nov 2016. Also saw a gyno in July 2016 about that specific issue. No help. Never got to the bottom of it.

An external ultrasound was done as the pap alone was a struggle and the gyno felt i “wasn’t ready” for a transvaginal ultrasound. Nothing was found. More and more I’m beginning to think I need the transvaginal ultrasound. The past 1 yr 4 months I’ve developed constant gas and bloating. There’s been some gastrointestinal change, where I now have huge farts daily at least 3 or 4 lying in bed. It began as soon as I can came off a low carb diet but has not gone away in almost over a yr in a half

Past 2-3 weeks I’ve had constant pressure in my left ribs that I think is coming up from the stomach.

Beginning to worry the problem may be ovarian cancer or the like. Are there further ways to investigate this aside from a transvaginal ultrasound? A CT scan/ MRI of the pelvic region and CA-125 blood test?

Annoyed that I’ve been shrugged off on this for so long

What specific tests should I ask for and where should I go from here?
