Aiyah, don't worry too much lah, a few of us in my mum group had fibroids during pregnancy and most of the time they just stay put or even shrink after delivery, especially the smaller ones like yours. I know it's scary first time hearing this, but honestly many pregnancies go smoothly even with fibroids, so just follow your doc's advice and do that repeat scan next month to monitor. The waiting in between is the hardest part I tell you, I'd be the same, but try not to stress because that doesn't help baby either. Maybe talk to your gynae again about what the plan is if it does grow, just so you feel more in control and less anxious. Take it one scan at a time, mama, you've got this.
