Adjustment of Status - I-485

Hi all, please help because me and my wife are very very paranoid.

I am a 23 year old male, born here in USA. Wife is 22 year old female born in china. I am indian she is chinese. She is on F1 student Visa, graduated last sunday, the F1 expires one month after graduation so Technically by June 19th. We met in July 2018, fell in love fast and got married in November 2018. Now this is where my AOS timeline starts :

March 22 2019 - Petition date, The USCIS received the I-485 and all our supporting evidence
2 weeks Later ( First week of April ) - Biometrics
End of April 2019 - Interview ready to be scheduled
First week of May 2019 - Interview has been scheduled ( June 19, 2019 )

Ive been a silent reader on here for a while, and ive never heard of getting an interview within 2.5 months of the petition date. What is going on ? I love her very much even though I fear the USCIS believes we filed for AOS 3 months before her F1 expires and may be suspicious, paired with the fact we got married 4 months after meeting each other. Im concerned thats why the interview came so fast. WE ARE WORRIED SICK, I have a lot of supporting documents however

- Joint Lease
- Joint Bank statement
-401K beneficiary
- shes a authorized user on my credit card ( she has no SSN )
- shes my emergency contact for employer
- she is on my health insurance
- joint utility bill
- 4 affidavits from family and friends
- pictures
-photos
- TAXES FOR 2019 WERE FILED MARRIED FILING SEPARATELY HOWEVER, she does not have a SSN and I reluctantly filed it fast.

What do you all think ?? Do you think the USCIS scheduled the interview very fast because they already deemed this an auto deny marriage and now just want to minimize her time in the united states ? they did not give her a travel document or EAD card yet.
