My mom had to deal with this, and she tried all the non-surgical methods - a pessary (device inserted to support the uterus), Kegals, etc. None of them worked well enough and she had to have a hysterectomy (removing only her uterus, not her ovaries), and they anchored her cervix to the abdominal wall so that it couldn't fall down. Your OB/GYN should be able to help you determine the most appropriate treatment, so you can try several things and hopefully find one that works. Surgery is, of course, a last resort, but sometimes it is necessary, as it was in my mom's case.
