3 days late to take my birth control

So I accidentally forgot my birth control when I went on vacation and I missed 3 days and I took them all like 30 mins ago plus the one I had to take today so I took 4 pills all together i should've looked it up idk if I should've did that but I started bleeding like 5 mins ago and I'm not sure like? Any advice? This just never happen to me I'm always on time to take it.
