I am currently 12w3d with my second baby. And I cant really keep anything down. I literally throw everything up. The past few days I have felt extremely weak with extreme dizziness. My mouth stays dry and I feel thirsty all the time. I can only drink ice cold water. My doctor gave me some medicine for vomiting but it doesn't help. I dont know what to do any more. Nothing I do seems to help... I'm scared my baby isn't getting the what he/she needs.
