8weeks and scared

So I've already been having cramps since week 6 and they get bad sometimes well today I've been sick and haven't been able to get any fluids down and my cramps got bad so I called doctor she said it happens when you get dehydrated while pregnant and not to worry just to try and drink as much as possible. Well I was laying on the bed and my 80lb pitty accidentally jumped on my belly, now I'm scared something is going to happen because I'm still having cramps but when I call doctor she just keeps saying g that the cramps are from dehydration. Did anyone else's pups jump on stomach at 8weeks and have a good pregnancy. Did anyone else get sick while pregnant and lose the ability to get fluids and baby be okay.
