Normal blood sugars during pregnancy are actually a bit lower than when not pregnant.
during pregnancy, following are the target blood sugars:-
fasting and before eating < 95 (ideally in the mid 70s -80s).
1 1/2 - 2 hours Post eating < 120, ideally < 100.
Never above 140.
Continue your monitoring. Avoid any foods that make your blood sugar rise above 140.
If your fasting is consistently above 95 or your post eating above 120, then your Dr may consider starting you on medications. Your blood sugar may get harder to control as the pregnancy continues, so please continue monitoring.
You may find it helps to reduce the amount of carbs you eat - eat more healthy fats and proteins instead. A 30 minute walk after eating may also help in controlling blood sugars.
Hope this helps.
