Taking birth control late..?

Nicole
I usually take my birth control pills around 3pm (it's been usually around 4:30 though) but today I couldn't take it until 7:30pm will the pill still be as effective? I did have sex last night (didn't cum inside me and no condom but the sex was only like 10 seconds b/c he wasn't "hard" enough) but is there a really good chance that I could be pregnant? I just started my seventh birth control pill pack on Sunday, October 26 and today is Saturday, November 1....could I get pregnant since I took the pill late today??
