Can i stay on my current insulin dose if my GD is already controlled?

i’m 24 weeks, diagnosed two weeks ago. started on insulin that’s supposed to escalate over time, but my numbers are tracking well - fasting low 90s, post meals staying around 135. nothing my OB has flagged as off. but the protocol says i’m supposed to increase the dose soon, and i’m wondering if that’s just standard procedure or if there’s something about pregnancy management i’m missing. is escalating the insulin mandatory when your numbers are already stable? i’m high-risk already and the idea of messing with something that’s working makes me anxious. fwiw has anyone stayed on their current dose when it was tracking well, or is the increase the standard move?
