I have 4 and my youngest was a "surprise". I hadn't noticed a huge difference after my third (who was 7 when #4 was born). Anyway, I figured with the vaginal births, once I got older, I may have some bladder issues due to the pregnancies. Well, about a month after my fourth was born, I noticed a "weird feeling" down there. I had a look (which I had never done before) and was mortified! I basically freaked out. Soooooo not normal! Well, I got in an appt with my midwife, who was very laid back about it. She said eventually it would probably go back...up? I should do kegel's and in a few months or so, should be back to normal-(whatever normal is for me at this point. ) She was right, after a few months, I no longer had the fear of finding my uterus lying in my underwear. *I will admit that with this being my 4th child and a very, very busy schedule with the older kids, I did NOT take it easy after the birth. In fact, since 2 days after my daughter's birth was Easter, we were out of the hospital within 24 hrs. I hit the ground running. Maybe I should have rested a bit??
Now, while things are better down there, I still have issues. I went to a surgeon who said he could do a more temporary fix for me, but I would probably be back within 5-10 years. Or, a more permanent fix, but I would be laid up for at least 6 weeks. I have a toddler and a new job, so that would be a ...no. I can tell when I've been on my feet too long, when I've done too much lifitng, or basically "overdid it". It gets painful and I have to lay down. Just last night this happened. I worked an extra 10 hours this week, ran around for 4 hours working the concession stand at my son's game - and I felt it! Also, my periods can be more uncomfortable, so I went on birth control (hubby had vas). It could also be that I'm closer to menopause.....yay! LOL! Now, for even more TMI - my BM's.....can be SUPER painful! Not like hemorrhoids, but inside. Ouch. Almost brings me too tears some days. I assume it's due to all the organs lying on top of each other and certain passage ways not standard anatomy anymore.
Basically, yes, things are different. It's unfortunate, that after all the pain and misery we sometimes go through during the pregnancy and birth, we are still left with such.....scars :( It will get better. You can lead a completely normal existance while having a prolapse. (I'm assuming you have at least a mild one at this point - midwife told me most women do after giving birth - to varying degrees) Kegel's will help. Plus time. If you are really active (what mom of 4 ISN'T???? :) you may notice it more. I'm a runner, too, so I deal with it on a daily basis. If it gets worse, I will go back too the surgeon. But, for now, I tell myself it's the price paid for 4 beautiful, wonderful children. At least that's my story and I'm sticking to it! Ha ha :)
*I apologize for the TMI, but I would have loved to know of someone else who had gone through what I was dealing with, so I just put it all out there!
** My midwife said that there have been some women who's uterus actually follows the baby OUT of the body with the birth. It has to be pushed back in. I felt very lucky after hearing that.
