Is this high for GD?


I was diagnosed with gestational diabetes the other day at my 34 week appointment. Today was day two of checking my sugar. Yesterday was 86 for fasting then 139 and 155 two hours after eating breakfast and dinner. Today my sugar dropped really bad because I tried to cut out soda cold turkey for two days. After getting it back up with two sodas, a burger and cheese fries it’s 144. Is that good for what all I ate and drank? I feel like after seeing my dads never get below 200 my sugar is doing pretty well but I could be wrong. I just hope that the doctors will understand I’m learning and since I’m almost done with my pregnancy won’t put me on insulin.
