Extreme morning sickness and diarrhea

Kayla
I am 7weeks today and morning sickness has been really beating me down. I can barely eat and drink everything comes back up. They are putting me on a small dose of zofran every 6 hours as needed. On top of the vomiting yesterday I started to have server diarrhea . I've never felt so week and hungry ever! I could cry , going to ER some point today if med doesn't seem to work. Are there any other ladies out there dealing with this problem also, and how are you getting through this ??
