Week 11 and lost 5kg

I'm on week 11 and I cannot eat anything. I had loss of appetite since my earlier weeks but it now got worse. Each time i try to eat, i feel like throwing up. I try to take small meals or snacks but i can't seem to eat at all. And i have been throwing up lots of burps of air and bile. Dilectin does not work for me. I've lost 5kg and I'm kinda depressed on how im not eating. My next gynae appointment is one month's away..not sure if i should see a normal GP or schedule an earlier appointment with gynae.
