Pain in belly

Mckayla • Mia and Noah❤️

So im 36w &1d and within these past 3 days I’ve been having this aching pain down the right side of my belly. Usually when I stand but sometimes when I’m sitting too. I’m not too sure it’s round ligament pain because I’ve felt that before and that to me is more of a sharp pull. I do have a 1 year old who’s about 25 pounds and I carry her on the right side and I’m also always picking her up from the floor to do things. I have a dr app Wednesday though so we’ll see🤷🏽‍♀️ anyone else ever experience this??
