Pregnant and hypoglycemic…worried about effects on baby

So I’ve been eating for heat and such which must have made me more fertile because I unexpectedly got pregnant. I’m 9 weeks along and my hypoglycemia is terrible. I have to eat a very heavy meal at night or I will wake up at 3 am and stay up forever. I have to eat first thing when I wake up or I’ll feel awful. Sometimes I wake up with low blood sugar headaches. I recently read this article on low birth weight and hypoglycemia http://everydaylife.globalpost.com/mothers-low-blood-sugar-affect-babys-development-17165.html and it freaked me out because all of my babies have been lower birth weight and hit their milestones slowly. Any advice on what I can do to turn this around while pregnant?
