Cassie, re the incontinence, my 10 yo DD was suffering a bit of dribbling so we got a referral to the incontinence nurses and I discovered due to the line of questioning that she took that there can be lots of different reasons, anything from the message from the bladder not getting to the brain, or a habit of holding the wee in so tightly all the time that it's impossible to hold any harder when you really do need to go, kwim? She was given exercises involving learning to tap her bladder to work out when she really needed to go to the toilet, to retrain her body to feel and respond to the correct sensations. So it could be any number of things and I'm pretty sure that a good incontinence nurse or physio will be able to help you, no matter what the problem is. Oh and the other thing is, you might feel like the only 22 yo in the planet with this problem but it's pretty common. No one ever talks about it though.

Cassie, re the pain, it could be from something as simple as where your cervix is sitting, or it might be something like an ovarian cyst (that often go away by themselves but need to be monitored). If I were you, I'd be seeing my GP about it BEFORE your bladder ultrasound because I'm betting the Dr will order another ultrasound to check the rest of your pelvic organs. Better (and less expensive) to get it all over and done with in one ultrasound appt, kwim?
