Ayyy jangan risau sangat, gestational diabetes ni memang boleh happen tiba2 even kalau takde family history, it's the pregnancy hormones doing their thing, bukan salah kau! A few of my mum friends pun kena the same thing first trimester then normal balik, so try not to stress yourself out because that makes it harder to manage. The good news is your readings aren't super high yet, tapi definitely worth checking with your doctor or the clinic to do the proper glucose tolerance test (bukan just random readings), mereka boleh refer you to a dietitian who can give you actual meal plan yang kena untuk your situation, because everyone's body responds differently. In the meantime, tips macam smaller frequent meals, cut down on sugary drinks & carbs yang refine, and move sikit sikit after makan, most of my friends managed it dengan lifestyle changes je without meds. You're gonna be fine, mama!
