Sugar levels high, So Scared!

Lisa
Im 38 and this is mine and my fiance's first pregnancy in 18 years together. Im diabetic and 7 weeks today. My sugar levels have been in check for a long time but as soon as I found out I was having a baby my PC took me off my main medicine, byetta. Its a class C. I dont have another OB appt until March 31st. All Ive had was my intial first appt to confirm that I was pregnant. I called yesterday and they didnt call me back. Should I go to the hospital? I dont want to hurt my baby because my levels are high. 😢
