Is that supposed to be there?

So this is a random question, but I genuinely don’t know what it is. There seems to be something blocking the opening of my vagina. It is squishy and doesn’t hurt to push on it. It is coarse feeling and not smooth? Rounded like a ball shape. Am I prolapsing or is the a normal pregnancy thing? Sorry if TMI! I just wasn’t sure and don’t go to dr til Thursday. Even then I am only 34 weeks so don’t think they check me yet.
