Am I Pregnant?

Ok, so my boyfriend and I had unprotected sex on Friday the 10th of November. He pulled out before coming. (Which I know is still so stupid, god I hate myself for this). I was due on my period on the 16th November, which was Thursday. I took a pregnancy test that night after not coming on my period that day and got a negative. It’s now Saturday and still no period, (but my cycles do tend to be very irregular by the way!!) and I have not experienced any symptoms. Did I take the test too early? It was 6 days after having unprotected sex, which does seem really early.. :/ I don’t know what to do because I’m really scared, someone help!!
