Just need an unbiased opinion

Hello all! This is my first post and I've been lurking on multiple different pregnancy related subs for the past few days, trying to weigh realistically if I am or am not pregnant while also trying not to look too much into it and get my hopes up.

TL;DR: I had sex Sep 23-24th and ovulated sep 25th. How likely is it that I am pregnant and when should I test?

I track my cycle via BBT and CM (can provide photos and legends of my tracking) My cycles tend to be longer around 35 days long and my periods last between 3-5 days. My husband and I are not currently TTC, but also do not actively prevent it as we are not against having a child.

I was not expecting to ovulate until around Sep 30th, and my husband and I had sex Sep 23-24th without pulling out. I ended up ovulating Sep 25th. I am currently 7DPO, first day of last period was Sep 7 (period lasted from 9/7-9/10).

Reasonably, is there a chance I am not pregnant? If I am pregnant, I should not be experiencing any symptoms until tomorrow at the earliest, correct? Anything else is typically cycle stuff and/or in my head?

TYIA!
