Gestational diabetes with twins

Amanda
Just took my glucose tolerance test this morning and failed miserably. I didn't even get past the fasting glucose check. They couldn't tell me my levels just I wasn't in range. Have to wait until my doctors appointment next week. Any other moms pregnant with twins and have gestational diabetes? Not sure what to expect. I haven't been able to exercise due to vasaprevia but I believe I eat well...salmon, chicken, fruits and veggies, egg sandwiches. Am I going to have to give myself insulin?
