Just got the call from my doctor's office saying my results from glucose testing came back as abnormal at 151. Have to go for a 3 hour test on Tuesday. I've never had any problems like this at all. Could this just be because of my pregnancy? I had no issues during pregnancy with my first son. Advice please! I'm freaking out! ☹️😰😱

Edit: Thank you all so much for the insight & advice! I feel so much better! Hopefully I pass the 3 hour with flying colors but even if I don't, I won't be worried because my diet is already on point. So not much altering for me to do. I'm honestly looking forward to carb loading though 😬🤗
