Pelvic prolapse

So, I'm super nervous to even post this, very embarrassed and humiliated, even... This is my 2nd pregnancy, almost 36 weeks. No trouble really w first go round. I did tear during delivery, but healed well.  Past couple of days, I've noticed my vagina is more swollen. Yesterday and today, I'm noticing something protruding from my vagina. I still have a week until my next ob appt. Wondering if anyone else is or has experienced this. I'm praying its more normal swelling rather than my pelvic floor coming out of me!! As though my weight gain wasn't less confidence for me, if my cagina falls out, I think I'll want to die! Not really die, but a little inside, anyway...
