When should I test

Hi I wanted some feed back on how long should I wait til I take a pregnancy test .. I had sex June 26th which was cycle day 13 for me .. I had brown spotting the June 27th and 28th (cycle day 14&15) . I didn’t feel any different until about July 7th when I realize my boobs feel ALOT more heavy than they normally are and one day I had this burning tingly sensation in my boobs but it didn’t last too long (my boobs are big but I can tell when they are bigger than normal) they always get sore sometime . My cycle is between 28-30 days . When should I test ?
