Fell.. 35 weeks pregnant.

So I was trying to carry my 2-1/2 year old to the car because he didn't have shoes on this morning and fell down to me knees. Do you think this did any harm? I haven't had any signs that it did any harm other than my knees hurting pretty bad. I do go the Dr this afternoon so I plan on letting them know but should I call sooner or go get checked at the hospital to be safe? Like I said I feel fine and I felt baby moving shortly after the fall. Also, my 2 year old is fine too. He was more concerned he dropped his tablet 🤷🏼‍♀️.
