So confused..

Well its 4:45am my time my appointment is at 2:30pm lol I'm going to be so tired. Anyways I had my dating scan the 12th of November baby was 8 weeks 2 days but I would now be 11 weeks and 3 days current. But my app shows I'm 10 weeks even with the due date the ultrasound person gave me. Also I'm so nervous cause I havent been eating like I should... ik mom shame me what ever but the baby pukes everything up. Besides candy which I'm sure I am now a pre diabetic since my test results in early November showed 51. And the thing is 57 for pre diabetic. Oops but we will see. But my friend thinks they will admit me to the hospital since I still cant keep anything down. I'm eating one a day and that I am forcing myself to do. I am going to ask if I can take these meal drinks I seen at walmart and also get more vitamins that I'll be missing until I can eat properly.
