Hope it turns out to be nothing / something easy to solve for you both, quite nerve wracking waiting.
I've had a few 2 week wait things (mainly due to lots of bleeding from everywhere) so have had gynae x 2, bladder x 2 and bowel.
First appointment they normally discuss symptoms with you, I've normally had blood tests done in advance by doctor but if not these are generally done then as well as tests they can do there and then. Bladder was blood tests for cancer, urine test for infections that day then ct scan was ordered - was all clear but had a rare infection picked up privately which NHS had missed. So was just given 14 days antibiotics. When had on nHS they did a cystoscopy rather than CT, also clear, just inflamed.
Bowel it was discussing and sigmoidoscopy that day and then colonoscopy under anesthetic a week later - this one was private. All clear.
Gynae was a while back and NHS both times. Before both first appointments I had had scan at doctors surgery. Can't remember exactly what happened other than discussing it. In both cases scans showed fibroids and they then did uterine biopsies both times under generals which were clear. Second time they did an operation to remove fibroids whilst under general. That's obviously for uterine cancer, not sure what they do for ovarian - all though during pregnancy I had a growth on ovaries shown on a scan I had because of lots of bleeding and a big blood clot in uterus whilst pregnant and they did an ovarian cancer blood test so maybe that first of all.
Good luck for the appointments, it's far more often nothing than anything serious but best to get checked. Also if they take a long time to get back to you with results it's generally all clear, took 3 months to get my gynae results second time, first time was 2 days which scared me as normally you get told fast with bad news but was all clear.
