period came back

i had my period last week and it finished.. about five days later my boyfriend fingered me and i didn't really notice much, but my period came back a little.. not heavily but still a little. and then we had sex with a condom and its still there. its not heavy, but this has never happened before so idk what it is.. i've had my period for about 6 years but its never been on a regular schedule..are these any side effects of pregnancy or am i just paranoid?
