Trying to get pregnant while on dialysis waiting for 3rd kidney transplant

I'm a 30 year old female and am have been doing dialysis now for 10years. I am currently awaiting my 3rd kidney transplant & I am engaged. There is nothing I want more in this world than to be a mother I have consulted with my doctors & they are willing to help me try to have a baby but due to dialysis it makes it very hard due to irregular periods & low hormone levels. I guess I just feel like my biological clock is ticking & I am losing my chance to become pregnant. Would love some prayers & positive support or if anyone has had this same struggles some advice. Thank you for your time ?
