Thank you for your query.
Cramps alongwith leakage of watery fluid could point towards an impending abortion.
You should see your gynecologist immediately to look for cervical dilatation or other changes on the ultrasound
Also, in absence of threatened abortion
, this could be a pelvic infection which is causing cramps alongwith watery vaginal discharge
This also would be confirmed by clinical examination and appropriate swab testing.
Meanwhile it is possible that some amount of normal vaginal discharge is there, alongwith cramps due to an increased gastrointestinal motility or infection.
However, considering the first possibility of threatened abortion, please consult your doctor immediately.
