Early pregnancy symptoms

Hi there I’m trying for baby 1. Had a miscarriage a couple years back. Just come off the pill 2 months. However I’m already starting to feel abit sick. 2 months into coming off the pill. I was just wondering what were your really really early pregnancy symptoms. For example when I had my miscarriage I knew I was pregnant because I had like a twinge in my pelvis. Three weeks in. Wasn’t sure if there was anything else I should look out for. Thank you.
