😬😭 Super confused about gastroenteritis...??

So, 9 days ago, I went to the Er & was told I had the "stomach flu". Should I still be feeling nauseous all the time from this or is this just pregnancy nausea?? I haven't had a fever or diarrhea and can hold down liquids ever since I went to the hospital & got rehydrated.

I'm just really worried about this pregnancy. It's been such a long time since I was pregnant with my son. Just anxious and feeling sick is really the only thing that feels like I'm pregnant... Other than sleep being a pain in the ass.

I've read so many different things, some sources say gastroenteritis can last 3-8 days, some say weeks. 🤷🤷

If anyone has any input, I'd really appreciate it.
