Stomach bug?

Is anyone else dealing with this? First my son had it and I assumed it was C Diff, just because I’ve worked with it in healthcare. I brought him in and they told me to wait it out.. that was a week ago and he had already had it for 3-4 days. Now I have it, and I’m pregnant. It’s super painful and I’m so dehydrated but I can’t even get up to let the dog out or anything. It’s terrible..

I had the stomach flu weeks ago so I didn’t think I’d get that this soon again.
