I am very nervous about possible pregnancy

I have been on the pill for exactly 1 month and 1 day, on ortho tricyclen. I just started my second pack of pills today, the active pills. I just had my period about 4 days ago. My boyfriend and I today had unprotected sex (meaning he was not wearing a condom) and he came in me twice. I am worried that my decision was a very bad one, and that i might become pregnant? I read from previous posts that you can become pregnant and are more suseptible to becoming pregnant the week following your period. I also know that the three weeks of active pills provide enough protection for the last week of unactive pills, or the time you have your period. I am also concerned because I was not consistent with the time I took my pills everyday. I take my pills everyday roughly within 3 hours of a similar time, so anywhere from around 8-11 p.m. however some times I do not take the pill at that time, on the weekends i tend to take it at around noon, and I am worried that this inconsistency is also a problem.
should i be worried? I know that 8% of women could get pregnant even though they're on the pill.
please help me out!

Don't think of it as a bad thing. There's nothing bad about being pregnant and/or having children. It's life. You just move on. Do what you have to do to make your life easy with the child whether you're alone or not alone. That child or those children will become you in the smallest form and deserves your love and undivided attention. Congrats if so.
