pregnant or not?

about 2 weeks ago my boyfriend and I had unprotected sex & he did pull out right before he did a slightest bit of cum did in fact go in me.. I've missed my period & taken pregnancy test & either they've come out negative or they have faint lines.. 3 days ago we tried again.. this time he let go in me not once but twice.. & I just got what seems to be my period a few hours ago anyone knows what this means?
