Late period, negative test, pregnant or late????

Felicia
I had my last period in February from the 1st-7th then I started light spotting from the 19th-23rd 
I was supposed to start my period on the 1st of march so I'm about 3 days late I took a pregnancy test this morning and it came back as negative, I've had unprotected sext about 6 time in Feb and used the "pull out" method , is there a chance I'm pregnant or just late????
