Could I be pregnant ?

My period ended 2 weeks ago I had unprotected sex 7 days ago BUT the tip only went in for a minute! The whole penis didn’t go in but than few days later I was ovulating and I had some blood wasn’t a lot but there was some when I wiped there was only blood twice when I went toilet than there was no more. I don’t think I’m pregnant because he didn’t cum in me but I am getting paranoid hahahahaha
