Hi, I couldn't read and run, I want to say I'm sorry you have faced this issue. Frankly, I have no idea how it feels to have a diabetes but I believe you will find a way out. I suppose you should better consult a doctor who is a specialist with this issue.
I just found that some medicines used in managing diabetes should NOT be taken by pregnant women. If you are on a statin, ACE inhibitor or similar blood pressure tablets you must tell your doctor if you plan to become pregnant or immediately you find out that you are pregnant, as these may harm your baby.
Many medicines used for blood glucose (also called blood sugar) control in Type 2 diabetes should not be taken in pregnancy so you may need to switch to insulin injections to control your blood sugar before or as soon as you find out you are pregnant. After the birth, you can usually return to your pre-pregnancy medications. Your doctor will tell you whether or not you need to change your medications.
