Prolapse uterus and pain. Again?

Im 155 cm and 89 kg. Obese for long. I had a complicated pregnancy with hypothyroidism, heparin injections daily, immunoglobulin and hormones injection, HCG, prgestterone etc. Because of repetitive early miscarriages in 2014-16. Finally 2016 I gave birth. I fall sick easily and have had breast lumps and surgeries post birth too. I even had bells palsy post birth  It's been four years now. Last year I noticed my bladder or uterus is prolpased mildly. Now its beginning to hurt and have cramps now and then. I also have severe backache for last four years since pregnancy. I also get frequent joint aches and no strength in my body. I know I have to lose weight before planning child. Is there any way to correct this prolapse before I try to conceive again? Anything to help. The backpain and lower abdomen pain is too much. I can't bend even to reach for something on the table. I can't lie flat on my back. Always to the left only.
