Possible Amniotic Fluid Leakage? 38w2d Advice!!!!

Rebecca
Okay , so last sunday my husband and I had sex. He also did ejaculate in me. Ever since we had sex that night i have been having this constant wet feeling down there. Nothing leaks down my legs or anything but it does cause me to have to keep wiping it. Im not sure if its discharge or fluid? I know its not urine. It is clear and watery. Im nervous to call my OB because everytime i worry about something it literally always ends up being nothing. Any advice????
