Hi Becky,
I had the same problem, I also had restless legs so I was up at 4am, and my sugars were perfect, then by 7am, they were sky high (7-9) its really hard to get them down, so I would have a correction dose and nothing worked. My HBA1c is still good at 5.8, and I am now 34 weeks, but the diabetic team said theres not much you can do about that if you are on MDI rather than a pump. So for the moment, I am still increasing my lantus every few days giving 3 days at the same unit to let it settle. Its a tricky time the 24 weeks mark!! Good luck!
