Am I pregnant?

Barbara • Mila

I always have 4 day regular period cycles, however, on the 12th of October I had unprotected sex, and my partner did ejaculate in me ( not the smartest idea I know ) but it was two days before my period. After that, I had my period though it was different, less blood and it lasted 3 days this time. Now, November 8th, I’m supposed to be on my second to last day of my period but I did not get my period. Can anyone help me understand this?
