Hi
@beccadry
Congratulations on your pregnancy

It sounds like you've made a good start getting your sugars down.
My tips for getting tight control are to test frequently. That way if you do get a high then you can have a correction dose of insulin (check with your DSN if you're unsure about that). In particular, test after every meal to make sure your blood sugar isn't spiking. I think controlling spikes was key to my good control in pregnancy.
Also, test at night. I got up around 2am to test every night. That way I could spot hypos and treat them quickly, and, later on, I could also make sure my nighttime basals were right. Remember that the night is a third of the 24 hr day so keeping your sugars in range then too will be a big help.
Also, be ready to adjust your insulin and your ratios as necessary. Pregnancy messes with your body - early on you'll probably be more prone to get hypos, but later you'll become more resistant to insulin and have to put your basal and boluses up a lot. Knowing that helps you prepare and keep control.
I had a mid-morning and a mid-afternoon snack almost every day when I was pregnant. I didn't find they pushed my sugars high. But I did stick to approx 30g or less carbs for those snacks, usually around 20g carbs. If you're hungry and want no/low carb snacks, try hard boiled eggs, or cheddar cheese. I combined them with a few carbs eg a digestive biscuit or two with cheese on top. This kept the carbs down but filled me up. 200ml of full fat milk heated in a mug with a spoonful,of decaff coffee made a nice snack too and is only 10g carbs, but satisfying. Nuts are good and low carb. You can combine something like slices of red pepper with chunks of cheese too.
It is hard being pregnant because if you're anything like I was, you'll want to eat lots or eat particular things, and having to think about your blood sugar is annoying.
Don't limit what you eat. Your body and your baby needs good food to grow. All you have to do is balance your food with your insulin. I know that's easier said than done! You'll never get every single test in range, but if you work hard and take as much insulin as you need, you should get most results there
Another tip is to keep hypo treatments near, including at night. Pregnancy hypos can surprise you. Some days early on I ate lots of sweets to keep my sugars up. I also kept Lucozade by my bed.
Finally, if you haven't already, get a 5mg tablet of folic acid from your doctor to take every day as directed, and get in touch with your DSN and hospital so you can get your ante natal appointments set up. My team were fantastic and really reassuring.
