posterior vaginal prolapse during pregnancy?

Has anybody ever had a posterior vaginal prolapse during pregnancy? does it effect or hurt the baby? how do you get it to go away? my OB’s office won’t be open until Monday so I can’t call and ask what to do.

if you don’t know what this is, here’s the definition

i have not been medically diagnosed with this but i felt pressure down there so i inserted my fingers down there to make sure everything felt normal, and i felt a huge bulge in the middle of the entry way of my vagina. i’ve had straining issues and trouble passing bowel movements in the last few weeks so i’m 99% sure this is what is wrong with me.

does anyone know anything about this and/or how it can effect pregnancy and the baby? and again, HOW do i get rid of this? what are the odds of actually needing it surgically corrected? i’m 23 weeks pregnant.
