Hi there. Do you mean you take your pills usually at 20:00 and you took it a bit late? I am positive that this is fine and you didn't risk pregnancy by taking it 49 minutes late! I'm glad you are responsible and taking birth control! Good for you! If you really worry a ton, you could use the birth control AND a back up condom (protects against std's too) but you are still protected by your pill even if taken a bit late.
