Amoxicillin lose stools

Ri

How long after being on amoxicillin did your baby's stools return to normal?

Our son had an allergic reaction to it on day 7 and had to stop. Waiting back from his pediatrician to tell us what to do next he has had 2 visits this week with his pediatrician for blood and mucus in his stool. Just want our baby to get healthy.
