Dramatic Weight Loss 😩

Before I Was Pregnant I Was 157 lbs . At My First Prenatal Appointment , I Was Down To 152 . My 3rd Appointment , I Was 147 . That Day Of My 3rd Appointment , I Had My Ultrasound , My Baby Was Big And Heart Rate In The 150s . AWSOME , What A Relief ! Now I Am 145 Pounds . The OB Said That If I Come Back To My 4th Appointment And I Loss Weight , They Have To Admit Me To The Hospital Because I Also Had Key Tones In My Urine Meaning I'm Not Eating , Drinking , or Throwing Up . But I'm Doing All Of Them Expect Throwing Up ! Could It Be Something Wrong With My Baby !? Or Is It Just Me ? HEEEEELLLLLLPPPPP !!!!!
