Is he less bloated or the same? I would do the bath once or twice a day and always follow up with a clean plain warm de-chlorinated soak afterwards.
Was his Urine clear and normal? Or did it smell bad?
EDIT; You say he acted as if trying to poop?? Did he sprawl his legs to the sides and shimmy his hips?? Describe his behavior. He'd up and eyes closed?? That's not normally how they poop?
Give more details. I'm also going to suggest you take him to a vet before performing any more baths because that behavior seems very odd to me.
