Need help asap!

okay so i'm on a combination pill and i take it daily but the time varies from about 6pm to 12am. On the 14thday of my cycle me and my bf messed around. he rubbed his penis on my vagina while he was in boxers and i was naked, he fingered me (worried about precum on finger), about 3-6 days after this i had brown spotting and discharge. period due in 4 days and i took a test and it was negative, should i be ok?
