Confused !! Need help

Nichole
Okay ladies I had my period August.9 
An I had unprotected sex on the 19th couple days later I've been cramping like crazy feel like menstrual cramps but no bleeding what's so ever , 
Earlier today I went to the restroom , an when I wiped I see this , idk what it is !! It's not sticky it's more like watery fluid .  
Can y'all ladies tell me what this could be ? Plz !!!!
