This sounds like you are beginning to develop a urinary tract infection . An UTI can cause inflammation of the urethra and leakage or urine. It also causes mild bleeding from the inflamed tissues and abdominal pain.
Another cause could be cervical infection if you still have a cervix. An infection of the cervix can cause excessive discharge which may be thin and watery. Inflamed tissues from the infection can also cause pain and bleeding.
A urine test as well as an examination of eh cervix will help identify the cause.
