Is it normal to get skinny while pregnant ??

Bryanna
So ... today I gone into the doctor and I am shocked I am almost 11 weeks pregnant and shows that I am 83.3 kg ( 183 lb 10.3 oz ) before I got pregnant I was 189.0 kg should I be worried ?? What should I do ?? Is it normal for someone that was fat to get skinny or should I ask to be weighted again ??
