Bleeding from my bum should i go back to hospital

Molly
So ive been in hospital for a few days after server pain in my abdomen. They did all the blood and urine tests and couldnt find anything. They then refered me to the gyno who wants to do a scan on wednesday to see whats up. However i have been discharged today as i finally had bowl movement after 3 days of none. Since ive been home i have had the erge too poo a few times and nothing is coming out except bloody discharge. They used an ennimer earlier to help me poo. Should i be concerned and call 111 or wait till wednesday and bring it up
