I'm only 27weeks pregnant but over the last few days ibe been having like yellow discharge and diarrhea what could this mean?

You must go see a doctor or ask a family or friend I don't know if it could lead to anything bad nor can you the best thing to do is get it checked out to see if there's any problems and your pregnant too so you don't want anything to go wrong

I don't see how asking family or friends will help.

This is a MEDICAL problem and needs to be addressed by a medical professional.
