There is really no reason to check blood sugars regularly after birth if your blood sugars after delivery were normal. Many times the diabetes will again go away after birth, but if your diabetes came back in the 13th week, that is a sign that you have diabetes and not gestational diabetes this time. Generally, the goal in pregnancy is to keep the blood sugar in the low normal range. Most Drs. want the blood sugar between 60 and 90 throughout the day. If your sugars are higher, they may need to increase your insulin dose.
Many people go on a pump during pregnancy and do very well.
If your diabetes is here to stay, you'll need to make some lifestyle changes after the birth of your baby. If you are overweight, weight control is essential. You'll need to start checking your blood sugar frequently to attain and maintain good control. I don't know if you are observant, but diabetes can be very dangerous in women who have frequent pregnancies close together, because there is no chance for the body to return to normal functioning between pregnancies. If you want to communicate with me directly, I will be happy to try to help you get in control, within your Dr's orders.
