Pregnancy symptoms

Has anyone ever found out they were pregnant but did not have symptoms?

I'm 12 dpo AF due tomorrow or Saturday. I have no symptoms of af coming or that I could be pregnant. My first pregnancy I knew I was pregnant bc of slightly sensitive nipples no other symptoms. I know when af is coming cause I always have cramps. Now nothing 🤷‍♀️ Still hopeful but I don't know. It almost been a year TTC #2. Im getting frustrated.
