Worried

So my period is 3 days late and it’s suppose to end tomorrow and I have had nothing except being really hungry and emotional. And I get cramps sometimes but they don’t last for long. I already took two tests yesterday and they were both clearly negative. And yesterday made two weeks since my boyfriend came in me and it was on the last day of my fertile window. Should I test again? Is it too early? Idk it worries me. I know it could be stress but I’m not really that stressed
