Infant poop

Hi mummies, My baby is 22days old. 2 days ago, we changed her fomular from NaN opticpro HA to non HA stage 1. We changed it cause we felt that she doesn't have any sign of allergies and we initially bought the wrong type. She was constipated for about more than 12 hours after the 2nd day of Opticpro and recently had these 2 poos. Its more towards greenish yellow and soft clumps. Does it look okay or should I be worried? We are thinking to kiv cause we just changed her fomular and her body is adjusting.
