TMI - toilet issues!

SB
Hi all! Looking for some advice! I've been having diarrhoea for the last 2-3 weeks since I came out of hospital. I was on two lots of antibiotics which could be the reason I suppose, but I honestly (sorry tmi) haven't had a normal poo since before I was ill. I'm sure if it's something I should speak to the docs about or just don't worry about it? Any tips ? Is it normal in T3? 
Thank you
