Can I take birth control pills 3 hours earlier for a few days?

Hello. I've been taking birth control pills for a year and I always take it at the same time and I've never missed a pill. I take them at 11 o'clock, because it suits me best, but soon for 3 days I will not be there and I would not like to take them with me. Could I take them during these 3 days in the morning, eg at 8 o'clock and then take them again at 11 o'clock? Will this affect performance?
