SMA carrier odds

Naty

I found out I am a carrier of SMA. Spinal Muscular Atrophy. I was told if my husband has it our baby is at greater risk and will most likely have SMA. Im thinking though. What are the odds that he is a carrier too?

I feel like everything is a guessing game. We spoke about it and if he is a carrier we would terminate due to the fact some cases have low year expectancy and i dont think i could sit and watch my child go through that. Please no judgement.

Any advice ? On odds ? Etc ?
