Baby stool followed by blood mucus

My LO has been diarrhoea for quite long. I have bring him to see doctor, doctor has prescribe medicine to him. However, after taking it doesn’t seem to be better. Every feeding, he will poo. I thought is ok, and my in law is saying that is normal. But now, he is having blood mucus. Should I bring him to hospital A&E as now is midnight/ wait till morning go back to the baby clinic to see doctor? Because I want to see A&E now, but my husband is saying that we can just go clinic tomorrow morning. But I am so worry 😩😩 #firsttimemom
