Is this normal?

I’m currently 8 weeks and 3 days pregnant, for the past few weeks I haven’t been able to drink water as it doesn’t stay down, so I’ve been sticking to ginger ale as it’s the only thing I can keep down. I have extreme morning sickness like 24/7 😩 Anyways, I’ve been having diarrhea like 3-4 times a day, sometimes more and I’m just wondering, is that normal? Or should I be concerned. I’m just worried that I’m dehydrated and if I should go see my doctor or just let it pass?
