Confused

I usually talke my birth control pill at 8pm everyday and I was never late when I first started about 3 months ago, but I've been taking it late a lot, usually by about 3 hours. I'll take it at 8 one night then 10 the other night then 11 the next because I forget. My boyfriend is worried about me taking it late because he thinks I might get pregnant because it's effectiveness is decreased. So I guess my question is, is the pill really less effective if you're late? Would another birth control method be a better option?
