pregnant and feeling very sick

hello I found out I was pregnant a few weeks ago and I did start having some nausea (usually if I had gone long periods without eating) this week I just did a 180 and I can’t keep anything down. I have been vomiting even with nothing in my stomach. I’m super dehydrated and was wondering if there was anything you guys recommend? I can take water, some sips of Gatorade, and 1-2 ritz crackers but if I try to eat anymore I end up feeling sick. I am also super tired and have been sleeping roughly 12-13 hours a day but I know I need to eat and stay hydrated, I can’t just sleep the whole day. If there is anything that has worked for you guys please let me know, thanks in advance!
