Hi, Im 12 weeks pregnant and ive been vomiting everyday this week where as i hadnt really been vomiting as much before this week. however I can barely keep any food down everytime i eat i just end up vomiting it up straight away. i went to the doctors a few days ago because i had upper tummy pains and the doctor said i had gastric reflux and told me to take gaviscon which i have. the pain has stopped however, the vomiting hasnt and i have been feeling quite faint and dizzy and i have had a head ache for a few days. ive also lost quite some weight i was 50 kilos before i was pregnant and i had gone to to 52 or 53 kilos and now im back down to 48. is this normal or should i go to the hospital ?
