I found a provider with nice pics and good bio. New to my area. The problem is i cant verify her on any othersitesor groups
  What should i ask her to verify her ?   I scheduled a session now im having second thoughts Any advice

Question, why would you ask her to verify herself AFTER you made plans? Shouldn't this have been asked prior to setting something up? If you're not sure, ask and If she gets pissed then good for you, maybe you dodge a bullet..but asking after?
But I wanna ask, what if you ask...and she tells you that maybe we shouldn't meet....Then a month down the road she starts to get 10/10 reviews. Turns out she'd the real deal. What would you do?? Call her again with your tail between your legs?

I agree with Happy's comment. I think the only additional point to consider is your budget and the session cost. How unhappy will you be if you put money down but really don't like the results?  If it's money you can loose and not feel like it's changing anything for you tomorrow, unless you have some other things that are bothering you I say take the chance.

If the provider doesn't have reviews or info,  Google search comes up empty when you search the phone #, I would never schedule the appt.  

I’m a risk taker, but I always trust my gut. If you’re gut is telling you to walk away, then walk away.

I agree. You’re the consumer. If it doesn’t feel right don’t go.

Ask her for her website/social media/review info.  
If she is real this should not be an issue.  
You already know what I am going to say next but you guys really need to think with the big head first. Of course she is going to have nice pics and a good bio. She wants you to book with her. "She" might also be a random dude in India who has generated everything that gave you a woody using AI.  
I am assuming you found something that might be off as to why you are having second thoughts. Proceed with caution.

How far out did you schedule? Is it for tomorrow or next week? Can you cancel w/o a $ penalty or a "pissed her off" penalty?
.
I.e., a polite "I need to (cancel; delay; reschedule) our appointment. My company is undergoing some sudden changes and I've got several important meetings that week." or "... my (friend; relative) just went into the hospital and I'm on duty to provide a lot of support (in the hospital; at their house; to their kids; ...)."  "Thanks so much for understanding."
.
... hardly sounds as bad as "I don't know. 'I'm having second thoughts.' I need proof. Show me your badges!" "Badges? I don't got to show you no stinkin' badges! You are now on my official Do Not See list!"

When posting threads it’s important to share the relevant information and we can better assist. 🤔  
Smile for me! Personally, I would pass if the provider is not verifiable. The only way I would is if someone I knew personally could vouch for that individual person. Peace of mind is priceless.

If I can't verify a provider to my satisfaction, I'm not going to contact them ever. Let alone, schedule a session with them and then have 2nd thoughts about it.

I agree with one exception: if she doesn’t have reviews and you can’t find any real online presence then I wouldn’t be very worried about being blacklisted.

I had to look it up. There's a story about the name of that song. ... Upisde down, that's water over the Bridge.

When Clapton ((?) was composing the song, he intended to write the word "bridge" over the middle section of the song, which is a technical term songwriter's use for that part of the song.

No reviews = Either scammer or non-GFE with bad attitide and one shot on goal = PASS!

Well, here's a DIFFERENT story from a youtube: http://www.youtube.com/watch?v=TTluGUww7TU
Eric Clapton and George Harrison were co-writing the music and lyrics. GH had written the word "bridge" on the page (as mrfisher said, a musical "bridge" section). Clapton was looking at the page upside down and misread "bridge" as "badge" and started laughing, "What is Badge?" and they ended up calling the song "Badge."

I am always available for any client but do not ask me to verify myself after you set a "DATE".
