Late pill

I had sex last weekend with a condom and two days ago with and without a condom. I'm on the pill on week 3 of this pack but during the 1st week I took my pill 6hrs late but my packet said to take it asap and I'd still be protected, so is it normal that I'm a little worried? I don't think he came inside me either, but I'm getting some period like cramps, is this normal??
