Help 😫😫😫

I'm almost 9 weeks and I've been so sick since I found out before 5 weeks. I've eaten very little the passed two-three days. I can't drink water. All I can drink is coffee and I can only have one cup of that. Nothing is open until Tuesday and I need SOMETHING. I feel like death... I've tried 7up, vitamin b, ginger ale these things don't work. I've thought about going to the er but even then they can't give me a prescription for the next couple days..
