What does it mean?

Thought I was pregnant bc if a lot of cramps 2 weeks before my period. Had unprotected sex every day for 2weeks during and around ovulation week. Had my period heavy for 2 days and then lighter the 3rd and then spotting for 3 or so more days then I stopped for almost 2 days then I started spotting light pink and brown for the past 3 days.
