Anyone felt this before

Tee

I am one day DPO according to the app and I’m cramping, feeling nauseous and also hungry at the same time.. This is my first cycle TTC and a fist timer in all of this. Is this normal at all ?? anyone experienced this before??. I know it’s only day 1 but I’m feeling very anxious and nervous 😩. Also, when is the perfect time to test for Pregnancy ??

This is all so much maybe I’m just thinking about it too much.

Thank you
