Stacey, do ask your obstetrician or midwife to look at this. You are obviously worried and need reassurance, and if you are developing a prolapse they need to know. Usually a prolapse feels like a dragging heavy feeling in the vagina…like sitting on a ball.
After the birth you may find all this just goes back to normal, but its at your 6 week check that you need to discuss your concerns again if you still have them
