birth. control scare

I've been on birthcontrol for 3 months So I'm wondering about my period so I'm on the pill and I've taken it late maybe 3 times out of the month late but no later then 6mins and for the past few days I've been having some pinkish blood discharge but my period is gonna start in like 5 or 7 days according to my pill package . And me and my boyfriend always have raw sex and every time we have sex raw I never get pregnant so I'm wondering can I if I taken the pill late a couple of times . I have googled being late on the pill and it says you can be late up to 6 hrs  But I'm still freaking out
