Do people really get pregnancy symptoms this early?

All I keep seeing is women talking about how they have pregnancy symptoms like major nausea, food cravings, severe bloating and breast pain, etc etc, at like 2 dpo and up from there. Does that really happen? I have a hard time believing it and it just makes me so doubtful that I could be pregnant even though we timed sex perfectly this month with positive opk and I confirmed ovulation with bbt shift. I just feel nothing. No symptoms whatsoever. AF is due in 2 days for me and I am hoping and praying it stays away. TTC for 8 months and all I see is a new pregnant person almost every day!!! Feeling like giving up if it doesn't happen this month. I have attached a photo of my chart.
