Extreme vomiting and weight loss

Alicia

Hi all! So you can be honest and tell me if I’m overreacting (this is my first pregnancy and just about everything scares me.) Anyway, I’m just barely over 7 weeks along, and the morning sickness started about a week and a half ago. But in just that short time, I have lost almost 18 lbs because I cannot keep down even a cracker. I’ve at least been able to keep down water, until last night. Since about 7 last night I’ve vomited 5 times, and I can feel myself becoming so dehydrated. My first appointment is this coming Friday, should I just tough it out until then? Or go to the ER now? I don’t want them to just laugh me out because it’s only been about 12 hours of dehydration. But I literally cannot even keep down a sip. Coupled with the weight loss, it’s kind of scaring me and I don’t know what to do. Any advice would be appreciated. TIA ♥️
