So confused. And question about ultrasound

Danielle

I’m 12 days late. I tested negative on Monday so after that I stopped testing. Then had brown spotting when wiping a couple times the next day. I happen to be going to my first urologist appointment for some long term urinary health issues Monday morning. They asked me to stop downstairs for a kidney/bladder ultrasound first. Would it be wrong for me to ask the tech to take a peek at my uterus and see if there’s anything? Maybe she would just notice on her own if there was something? I’m not sure what to do. I’m waiting on more tests. I’ve never been this late before unless pregnant. I’ve also never had a successful pregnancy.
