Signs of a Miscarriage ?

A • Married to my high school sweetheart .Mommy of two doggies.. TTC for over 4 years with baby #1
Little backstory..I ovulated around the 20th of October...a week later after having sex I had bright red blood . It took me about three wipes to get rid of it (no clumps or pain, just bright red blood). 
Now my period is 4 days late. Does this sound like I possibly miscarried or possible pregnancy ? Taking a test today on my lunch break but I figured I would ask for other women's experiences
