Pregnant??

Hi, Im up thinking am I prego?? I cannot wait til morning to know! So, I had sex 4 weeks ago & at the time I wasn’t on my pill (no protection at all🥴).. A week after sex I still received my period. A week after that I started my BC again. Now it’s basically two weeks later since I started BC again & I spotted today (brown discharge) though during the week I took my BC off schedule. So now I am wondering am I pregnant or is it just pay back bc I took a pill off schedule..

Note: I’ve been on BC about a yr & a half so Im pretty sure it was still in my system when I had unprotected sex.
