Keep losing weight

My morning (all day) sickness is so soo bad. I've been on diclectin and it has been making me sleep throughout. I can't even eat proper food. Can't even have protein (white/red meat or fish). Only carb. I feel so guilty for not giving enough nutrition for my baby. And within 2 weeks, I've lost 2kg. Im at my 9weeks now. Is this even normal? 😢
