So I just weighed myself for the first time in a week, and my heart dropped because I seem to have loss 9 Ibs from my already 14 Ibs total since finding out I was pregnant I'm 18 weeks and 1 day so I shouldn't be loosing weight anymore I'm scared something is wrong I am not a big girl at all I'm very petite I went from 107 pre-pregnancy and now I weigh in at 93.5 I was very sick in early pregnancy and now I'm fine eating about 1800-2000 calories a day i have no idea what to do.
