Baby movements- 21 weeks- Dr. told me I should feel them everyday?

Hi everyone- i’m 21 weeks along. I had a Dr.’s appt. yesterday and told my doc that the baby has been moving since week 16- just not on a consistent, daily basis. He told me that from this point on, I should be feeling the baby move everyday and if I didn’t, to call him.

I just want to make sure I am interpreting the correct feelings down there…even though my uterus is behind my belly button right now (and, according to him, the top of the uterus is about 1-2 inches above my belly button) I am feeling the little gurgles/ flutters mostly in my lower left abdomen. The flutters haven’t moved too much out of that region since week 16. That’s the baby moving right? I am not mistaking it for gas bubbles am I? BTW, this is my first.

Thanks!
