help please!

Anyone experience uterine prolapse? I'm pretty sure that's what I have. I'm 3 weeks 4 days PP and 3 days ago I felt a "bulging" feeling down there and went to the bathroom- I can feel and see (with my phone) tissue at the entrance to my vag. I had started working out the Monday before- just two miles on the treadmill at a brisk pace as bleeding had stopped and my stitches had dissolved. I can't call the doc Today, they're closed for the holiday. I do NOT want to go thru life with this feeling and part of me "hanging out". I've been doing kegel exercises and whenever I go pee I start and stop the stream as much as I can to tighten the muscles. Ugh.
