Pill break through? Urgent need of advice


Hi, I'm 21 years old in a stable relationship and currently taking the pill.

I missed one pill on the 8th which was 2 weeks after my period ended and I had sex 3 times that day (wasn't aware that I missed it until the next day)... I missed another pill on the 16th and started spotting on the 17th for that day only... it's been two days since and I'm spotting again, but my period is due in 8 days. What does this mean? Is it hormone issues because I missed a pill? It's a light pink colour.. sometimes darker, I have slight cramps, but nothing major. Can anyone help?
