Ay, first time mommy, that's a valid worry, gestational diabetes is something they screen for during pregnancy, so maraming moms go through that checking process. It really depends sa marami factors like genetics, weight, age, at family history, so hindi lahat ng moms develop it kahit may risk factors. I'd say the best thing to do is follow your OB's advice on the glucose screening test (usually around 24-28 weeks) and eat balanced meals in the meantime, a few of my mum friends were anxious din about this, pero once they got tested, natugunan na agad ang concerns nila. Your doctor will have a clear picture once the results come back, so don't stress too much ahead of time, ha!
