Cather was too short for fet,it got cancelled

Has this happened to anyone? On my transfer day after 45-1hr trying to reach the uterus with embryos already loaded ,the doctor finally cancelled my fet and told me to loose weight

I thought this was it ,after I had a failed get in november (different doctor) also struggled to reach the uterus ,I'm now starting to think that's why my transfer failed

I was even sore and bleeding for 3days after this cancelled transfer, it burnt to pee

I'm meeting my doctor friday to discuss way forward is there anything I can suggest or say ,we have 6 embryos left but only 2 are good grade the rest poor
