I had a hysterectomy and removal of tubes/ovaries and cervix 7 years ago. However for the last 4 days I've had a dull pain in the area my cervix would be (vaginal cuff?) and a very very watery discharge. It's definitely not urine, it's got a very slight green tinge to it but literally it's like water. Any ideas? After my hysterectomy I was readmitted due to a haematoma/fistula in the cuff area but it was blood. Could it be an STD (I haven't cheated but have suspicions about my partner). There's no smell.
