Am I pregnant?

Lightt

I have one day till my period is missed I am constantly discharging this thick white discharge with no infection once so ever I had intercourse on the day I was peeking which what September 17th. My lower right side of my stomach has a knot and has been pulling for the past few days. Idk wtf this means I’ve always miscarried and I need someone to talk to about it beings I’ve never experienced the feeling! Someone please tell me what this is I’m experiencing? Thanks in advance.
