Can u feel baby at 9 weeks?

This may sound like a silly question but I am not trying to be funny, I promise ;) I was wondering if while lying flat on your back if you could feel a little ball or area where u know the baby is as early as 9 weeks?

I remember my sister telling me that you can feel this area that’s lower (it’s a little ball) and then it moves back up after you give birth until it’s back in the right spot. I know that’s not the same thing as the baby. But still.. I was just wondering if you could gently poke around and feel where the baby is? I’m not pregnant by the way. I’m just curious, or else I’d try it and see for myself 🤷‍♀️
