Feeling jittery a days after positive pregnancy test

Hi all wondering if anyone had insight. I got a positive pregnancy test after a frozen embryo transfer last Saturday. The next day, in the evening, I felt super jittery.

I couldn’t really sit still. My heart wasn’t raising like anxiety just jittery which made me feel so weird. It wasn’t low blood sugar. I ate a few hours before and was also at a Super Bowl party so a lot of food.

I’m nervous, I’ve had several chemical pregnancies and now all I can think about are those times I’ve gone to the bathroom started bleeding. Anyone experience this and it was alright?
