No soul when ur baby is 125 days old?

Mudasira

Is it true that during the 125 days the baby is in ur stomach , theirs no soul ? My daughter had a genetic condition and she passed away. However, I do have 25% chances of having a baby like my previous daughter in my current pregnancy so I have two options the doctor gave

1) terminating my pregnancy

2) for the baby to get a bone marrow transplant .

Obv I would be terminating my pregnancy for good reasons because I don't want my baby going through what my daughter did ( bloody stools , diarheaa . not latching , high fever, metabolic shock , not feeding for two months etc ).. but the doctor was trying to make me feel better by saying if I terminate the baby within 125 days of my pregnancy, I don't get sinned because the baby doesnt have a soul .'is that true ????

In this case i wouldn't even be worried about getting sinned but just out of curiosity I'm asking .
