I had unprotected sex on Halloween and my last day of my last period was the 20th of October. I started bleeding earlier today and it has been 2 weeks since i had unprotected sex and I was supposed to have my period on November 12th which was 2 days ago, and I've been looking up things about it and couldn't get a good enough answer. I'm just wondering, could I be pregnant? Or is there something else wrong? I just need a straight forward answer and everything.
