Could I be pregnant?

I’m five or six days late. I had sex right after my last period ended, and ovulation was a week later. Condom broke but I’m on birth control and it wasn’t ovulation time so we figured we were fine. Now my boobs are getting veiny, I’m bloated, I’m feeling sick and having headaches. I’m taking a pregnancy test tomorrow but I just want to know if I’m being paranoid. Thanks in advance.
