Well if it is a lump other than your cervix, a pap could be able to make the lump visible to the gyno. Thats honestly the only thing I can think of, Maybe an internal exam so the gyno can see if she feel's anything abnormal.
I hope that you can find out what it is, or atleast have it not bother you as much.
what exactly would the pap be able to show me?
It could have been your cervix, as it does change texture and shape during pregnancy.
I dont know if you can feel baby through your vagina, then again I never tried lol.
If it hurt, I think you should have your doc do a pap, to just make sure all is well.
