You need to see your doctor.
If only part of the uterus was removed and the tubes still feed to the uterus it maybe possible.
However the remainder of the uterus maybe to small to carry a child and you would risk a rupture which I can tell yu from personal experience is very painful and unpleasant not to mention life threatening.

Bleeding does not mean pregnancy is possible.

Have you been having unprotected sex since your surgury? If yes then I think you possibly only had the cervix remaining which you need to confirm with your doctor.

And sudden bleeding should alway be checked out - it could be endometriosis of the cervix causing it or maybe something else.

We on here are not doctors and can not review your case via an internet message please see your doctor as soon as possible.
