anemia and sugar !!!??

I am currently 27 weeks pregnant and my only conflict has been that they told me that my baby is on the bigger side. I was sent to get my blood glucose test to see if i have diabetes. I got a called today that my results were back and they told me that it shows that i have a little bit of anemia and that my sugar test was abnormal. So they told me to go back friday for another blood work. Should i be worried? im honestly really scared 😭 i want my baby to be healthy as possible
