Discharge: I would assume you do not have a discharge like this usually. Although you do not have and odor it does sound abnormal. Get checked.

Discharge/cramps: Several possibilities. You may be having problems from a pelvic infection causing the discharge and cramps. You need to call your doctor for an appt. for a pelvic exam and tests to find out what is wrong, and give you any necessary treatment.

GYN: you will need a GYN evaluation, pelvic exam, and a bacterial culture of the vaiginal discharge. Consider STD screening if sexually active and unprotected.
