Almost everyday or every other day I feel what I believe are my baby boys hiccups. It’s like a light rhythmic thumping and only lasts 10-15 minutes if even that long at all ( I can feel it with my hands as well most times )

I looked it up and it said that if they experience this too often there could be a cord obstruction? I am curious to hear what other people think/ their experiences so I can ask my dr tomorrow.
