I am 23 yrs old and have a 2 year old son and have EDS III. Pregnancy with EDS is not life-threatening. My mother has EDSIII and had 4 children. My pregnancy was extremely painful, but not life threatening. I had ruptured blood vessels as a result of my EDS and blead for 8 weeks. While it was scary, it was not life threatening.
EDS get worse after pregnancy because toward the end of your pregnancy your body releases a hormonoe called "relaxin" and after you have your baby your body is supposed to go back to normal, but that relaxin does permanent damage to EDS patients. Your joints loosen up and your hips spread to allow the baby to pass through the birth canal and then go back to normal. But with EDS you just don't go back to normal and your hip joints stay loose. It does get worse with each pregnancy, but it doesn't threaten life.
It is extremely painful, but even more than that it is extremely WORTH IT!
I visited with my specialist recently and she told me EDS patients should give birth early before the relaxin takes affect to avoid the damage. I had my son at 38 wks and they are recommending 37 for my next one.
Good luck to all and remember it's hard, but worth it!
