I was diagnosed with a prolapse uterus, my cervix has risen back?

I was diagnosed with a prolapse uterus 2nd degree where my cervix comes down to the opening of my vagina after giving birth to my 2nd child.
This particular month I noticed my cervix has risen back into my vagina which is me concerned
Which is something that has never happened
Typically my cervix hangs low I can feel it when I touch my vagina
This particular month my cervix has risen back into my vagina
I’m concerned as to why this happened
Any suggestion
