cramps and discharge (TMI)

Hey ladies,

The past couple days I have had light cramps with light watery discharge. Today I woke up and it was heavy discharge to the point it gushes out. Just now started getting intense cramps in my lower right side. Any ideas? Obviously will see a Dr if it persist.

Period isn't due until 09/16. I did have unprotected sex in 08/19 (last day of my period)
