Brief Answer:
Most probably bleeding and may be with infection.

Detailed Answer:
Hi.
Thanks for your query, albeit short and specific.
To recapitulate: Female/47 - liquid black stools .....
This is most indicated of a bleeding somewhere in the intestinal tract from oral cavity till mid colon. The blood is transformed into black during its passage through the intestinal tract.
Watery may indicate infection or due to blood irritating the intestines causing faster passage not allowing the absorption of water.

Hence I would advise you the following:
Need to go to ER/ Hospital for clinical evaluation, actual examination and investigations to determine the cause.
Tests of stool: Routine, microscopy, occult blood.
Tests of blood: CBC, liver and kidney functions and as may be asked by your Doctors.
Ultrasonography and CT scan if anything is suspected.
Upper GI Endoscopy and colonoscopy.

These will give the idea of what exactly is the problem so that a proper management can be done.

I hope this answer helps you, please feel free to ask for further relevant queries if you feel that there is a gap of communication.
