Your blood doesn't clot properly thereby making it impossible for the embryos created out of your sub-par eggs (coming out of your prematurely failing ovaries) to remain implanted in the uterus, thereby necessitating conception attempts to move from the bedroom to a sterile doctor's office (and pay thousands monthly for the experience) with a cast of six male doctors staring at your vagina while attempting to manipulate the catheter on any given visit. No one can tell you how long this will take or how much money you will spend or what your body will endure.
