please help! worried!

Abigail

I'm 12 weeks pregnant.. first time mum. I have suffered with awful sickness and as a result I have lost a stone and a half.. I have no appetite, just the thought of food makes me want to be sick, and now physically moving makes me feel nautious and nearly vomit. please please tell me this is normal? And what I can do to ease It? I'm really struggling to cope 😭
