Extreme Highs in Pregnancy

So, I am not really sure if I am pregnant yet - its WAY too early to tell I would only be 1 week along if I am actually pregnant. My HbA1C is not where dr’s want it to be - i am still hovering around a 7.5. Anyhow - I realized (after the fact) that i had sex the last day of ovulation and my sugars are totally out of whack right now…for instance…i went to bed last night at 92 and woke up at 3:30 this morning in the mid 300’s! I am so petrified - I was pregnant in the fall and miscarried at 7 weeks and I am convinced it was due to a few hours where I hit high numbers one day. Can anyone share advice, tips or success stories that will help calm my nerves for the next 2-3 weeks? Thanks in advance!

First off, take a deep breath! Everything will be ok. I know how hard it is thinking all those highs are not good for the baby. But if you get on target quickly, things met e just fine. There is no guarantees but I know when I was pregnant every high reading, I flipped but in the end I had two easy, happy pregnancies. You can do it! Keep us posted as it is still pretty early but I must say being a mom is my favorite job! Good luck!

I was pretty sure I was pregnant about a week in because my bgs were running high, and confirmed by pregnancy test not long after. I’ve definitely had a few high readings and I have a few times where my high bgs would be sticky and not come down for a few hours. I’m at 18 weeks tomorrow and everything is going well so far. My A1C was in good shape when I got pregnant, but I’ve seen lots of accounts of people who got pregnant with high A1Cs (8-10+) but had very healthy babies.

Just start upping your insulin until your bg comes down and stays down. I spent the first few weeks pregnant with higher temp basal rates, over-bolusing, and keeping a good supply of glucose tabs on hand.


  1. Breathe.
  2. Correct, correct, correct
  3. Monitor very closely. If you are pregnant highs and lows can both happen.
  4. Drink plenty of water
  5. Recommend eat low carb, to help reduce insulin requirements.

For me high blood sugar was the first sign of pregnancy with my second (with my first I didn’t find out about the diabetes until a few weeks in), literally within 24 hours of ovulation.

However, on the other hand, I have had positive pregnancy tests between No. 1 and No. 2 which didn’t result in high blood sugars… but those little ones didn’t stick.

Further, my blood sugar typically goes a bit crazy around period time anyway, so it’s really hard to jump to any conclusions at all. The joys of being a woman.

It doesn’t matter what your hba1c is as that is from the past 3 months. The only thing that matters is what you do from today on.

Best wishes.

Even if you turn out to not be pregnant, you should work on getting your BGs under tighter control. An A1c in the sevens isn’t doing your body any favors, pregnant or not. I wish you the absolute best regardless of the results of your pregnancy test!

Thanks Sally - still waiting to figure it all out - i did an at home test that was negative but I am still 6 days late (very unlike me) and my numbers are insane - super lows one day and today I can’t get under 200! I have an appt with my perinatologist tomorrow and blood work for Saturday to confirm…i am just so scared with organs and nervous systems and spine all potentially developing now…I am so scared of miscarrying again! Trying my best, doing temp basals at 130% with hopes to bring it down and just keep praying everything is ok!

Well, it’s been confirmed! I am 5 weeks today. Thankfully I was able to get into a perinatologist right away and they helped me adjust my basal rates - between that and cutting out simple carbs my sugars have been in tight control. Now I just have to remain positive and pray that all goes well until the first ultrasound…the waiting is scary!

Hi Tara,

good wishes to you and your little baking peanut. Keep us informed how you’re going. Seems like you’re on the right path.

Congrats and enjoy!, My bgs were high the first few weeks, thats how I knew I was pregnant. They then evened out from about week 8-12 and I was back to taking my pre-pregnancy doses. Everyone is different though. Good luck. :grin:
