Four days late

So I had sex and used condoms and six days later I was spotting but it was a lot? I think? And it was for three days or more I don't remember but now my period is late by four days. I had a few cramps last night and a few this morning but still no blood. My cervix feels open and high but there's still no blood!! I'll take a test asap, but can't rn. Could I have spotted enough that it affected my period? I don't feel pregnant but I know that doesn't matter in pregnancies lmao. Plus when we used the condoms there weren't any holes or tears and I'm p sure no cum got in me at any point. Why is my period so weird rn omg
