Kiddie costers and 17 weeks ?

I'm 17 weeks preg, not very big. I went on my senior trip yesterday.6 flags and knotts Barry farm. At 6 flags I went on so kiddie coster to Sharp turns or giant dips. It was fast but I didn't feel as if it was throwing me around cuz it didn't. At knotts there is this horse coster another baby one.30 seconds long and the two turns were wide and it was fast. This one it held ur torso in one spot. I can still feel the baby moving. A lot still. Could I have hurt the baby though, I haven't felt any pain at all and no blood. Just the baby moving like normal
