Pill HELP

Tatiana
This is my 2nd month on the pill Minastrin 24 fe and I am a perfect user. I haven't missed any pills and I have never been late. However, after taking my placebo pills during my last pack I still haven't received my period. I'm now 14 days late with dark brown and pink discharge. I don't know if this is breakthrough bleeding or spotting but hopefully not implantation bleeding. Can anybody explain to me what's happening?
Please don't tell me to take a test because of a missed period. I do understand that when taking the pill, women may or may not receive a period.
