Dropped @ 30 weeks?

Sara • 1st baby. 💎 scared, but excited!!!😍
I'm 30 weeks pregnant and the pressure in my pelvis is defiantly a new feeling to me... I'm a first time mom and I'm not sure about all this.But is it too early for my son to be dropped already?? When did your baby drop? Does it do anything about when ur baby arrives??. I'm on high risk and I'm just wondering if I should be worried or not..?
