I don’t know..?

So I get stomach cramps, back pain, tender breasts and nausea. I’m due on tomorrow and this time everything feels slightly different with fatigue as well and I also had unprotected sex while I was ovulating, he pulled out but I feel different in myself. Should I take a test if I don’t get my period tomorrow. Its not the end of the world if I’m pregnant I would be happy but not over the moon cuz it’s not the best timing but we also aren’t stopping it, yno?
