Could I be Pregnant?

Please do not be rude about what I am going to post:

Okay so about 2 weeks ago, me and my friend (guy) had oral sex and fingers were involved. Fast forward after he was done with me he started to masturbate and such. Adding on I asked him if his fingers were covered with pre-vim and his so did he put it back inside me. He was to busy to answer the questions. Later one I was home and I started to worry if he did pre cum and put his fingers back in. So yes I'm the type of person who Google's almost everything. So I looked up "Could a woman get pregnant from fingering" Yes I know it sound ridiculous but here me out. I found out from a medical source that "yes" it is possible but a very very VERY low chance of pregnancy. I started to feel anxious and worried and I have been since then. Fast forward to present day I told people who I could trust with this information about this information and they said based on the discription I gave them they all agree I should be fine and it's a very low chance of pregnancy. Even the doctor who I recently went to agree that I can not be pregnant. I told her I've been bloated,constipated, doubtful, etc. My last period was the 6th of Feb and "eve" the app a read that my period should be coming soon. My question to you guys is what could be making me still ferling like it's possible. Due more I have extreme anxiety.

Also another note we had oral Friday night on the eight of Feb.

Here are the photos of my belly

Also one last note I took 3 pregnancy test all came out not pregnant.
