Depending on where your baby and placenta are in your belly could affect how much you feel. So baby could be moving around a lot more than you realize. My little nugget moves around all day but not always 10 times within an hour.
But don't be afraid to call your doctor or ask as many questions as you want. It's better to be informed than clueless.
As long as your baby is moving at least. 10 times at the least a day, your baby is fine. And as your baby gets bigger he or she will be spreading and putting pressure on your diaphragm making it difficult to breath. Youll be fine.
