I usually have a period for 3 days this month it was 24 hours then i had a brown spotting 7 days later should you take a pregnancy test?

I WOULD TAKE A PREGNANCY TEST JUST TO BE ON THE SAFE SIDE. HOWEVER, IT ISN'T UNHEARD OF FOR WOMEN TO HAVE AN IRREGULAR PERIOD ONCE IN A WHILE. SOME WOMEN HAVE IRREGULAR PERIODS ALL THE TIME. HAS THIS EVER HAPPENED BEFORE? DID YOU START ANY NEW MEDICATIONS? DID YOU RECENTLY MOVE? IF YOU DO HAVE A PERIOD AGAIN WHEN IT IS TIME AND IT TOO IS IRREGULAR. CALL YOUR DOCTOR.
