L.S.
Good advice from Kathie.
You can grease everything with KY and shove it back in. if it doesn't hurt you to do that. (we do that sometimes at the hospital if necessary)
start doing lots of Kegal's and soft situps to tighten the abdomin and pelvic wall muscles.
can be surgically corrected. or you can wear an egg shaped thing in your vagina to hold everything in and up. it is called a pessiary(sp?). it is non-surgical intervention but has to be prescribed by a doctor.
but yes, with birth, large babies and straining, and picking up heavy things (including your little dumpling) can contribute to this. not an emergency unless you cannnot urinate. and make sure to try to empty your bladder when you go. a prolapsed bladder has a harder time emptying all the way because of the angle and prolapse. it will sometimes retain just enough urine to start a UTI, because a little bit is always left and incubates, so to speak. drink lots of fluids.
see the doctor as soon as possible.
good luck,
L.
