Weird! Help!!

I recently had paragrd removed a month ago. On the 25th I thought i strted my period. It was really light an pink and red like pink with red specks. I had unprotected sex with my bf the 2nd period day. And now today I have orange spotting. Idk if im already pregnant or about to ovulate or if it was just a period but it was really light and only about 2 maybe 3 days long. I have SLIGHT cramping too and my boobs feel sore like sore muscles when they are touched. Im 18 years old and have been with my bf for over 3 years.
