Feeling of fullness in vagina?

I am 6.5 weeks postpartum and started feeling a strange sensation a week ago like a tampon was not all the way in - I got freaked out and went into my OBGYN for an emergency appointment (thought I might have prolapse of some sort) but she said everything looked normal. It’s been another week and I STILL have this uncomfortable “full” feeling. Has anyone else experienced this or have any idea what it could be / how to make it go away?

I am desperate!
