So implantation bleeding? Should I test?

Last night I had unprotected sex and started spotting. Which is very rare in between periods. I use two different tracker apps and I’m not sure if it’s AF or implantation. When should I test? We had sex all through both fertile windows and on the day I tested pos for ovulation. Hellllppppp. Cramping and sore boobs, indigestion and some nausea
