PLEASE HELP! Missed 10 birth control pills!

Olivia
 I had posted earlier about being concerned I might be pregnant, I forgot to include that I had missed several pills this month due to being super busy. I had mentioned I've been experiencing breakthrough bleeding, nausea, cramps and headaches all week. I'm just curious what my chances are of being pregnant? Should I wait a week till my period is due or just take a test? I have 6 pills left in my birth control pack. Do I continue or stop taking those also?
