Diabetes in pregnancy

Does anyone ever feel like their sugars are too low after eating and pumping insulin then feel nauseated like you need more sugar in your system but when you check it's at the perfect numbers as where they should be? I have that problem a lot. Sometimes I feel a little weird too but then sugar is too high. It's so difficult managing any type of diabetes during pregnancy because you never feel good, you worry about high numbers, and when you get hypos you over indulge sometimes. Please tell me I'm not alone because I feel like I cant win.
