Possible TMI, prolapse or hemorrhoids?

So everytime I go to the bathroom (both pee and poo) I have a lump come out of my anus. I have to push it back up each time. Lately I've started sitting on the toilet longer to make sure all the pee is out otherwise I still feel like I have to pee and usually wind up back in the bathroom not long after. I didn't notice this happening until after I started sitting on the toilet longer. I'm 35 weeks and 1 day and this has been going on for at least a week. I don't have any bleeding or pain. It feels smooth not hard and no it's not poop. Anyone else experience this and what was it?
