Trip and fall while pregnant

I just tripped and fall in the bus due to the slippery floor. Luckily i managed to hold on to the pole, so i endes up falling to my knee and not down flat on stomach. But im currently 30 weeks pregnant. Should i go to the doctor still to get a check? Im not worried about myself, but the baby im carrying. I do feel some movement in the stomach, but still it's quite worrying. Any advice?
