HELP PLEASE!!

okay so I'm on the pill and me and my boyfriend had unprotected sex although he did pull out I'm still worried about pre cum and I also forgot to take the pill that night (after we had sex). my period is 2 days late and I'm having a little cramping and a little spotting and I don't know if that is because I'm about to start my period or because I'm pregnant. I just started birth control a week after my last period so I haven't had one on the pill yet so I don't know how light it is or when it will even come considering I started the pill in the middle of my cycle. but I'm freaking out because I don't know if I'm pregnant. the only symptoms I have would be the spotting and cramps but other than that nothing.
