At The Beginning Of This Birth Control Package I Missed

At the beginning of this birth control package i missed 2 days. But then i took 2 then 1 then 2 to catch myself up. I now have taken them at the same time every day for 6 days now (and have been on birth control for over 5 months all together). My boyfriend had sex but the condom broke and the sperm was in me. Should i take plan B tomorrow or do you think i will be fine since im on birth control? Im wondering since i messed up the first couple of days last week of a brand new package. Thank you so much. Im freaking out alot.
