At what point should I see the Dr for morning sickness?

I have been suffering for weeks. It’s gradually getting worse (I’m now 8 weeks) where I am sick two or three times a day. I find it very hard to eat and drinking water makes me nauseous. (I am very worried about my fluid intake) To top it all, I’m extremely consipated. Is morning sickness normally this bad? At what stage should I speak to my doctor about it?
