Missed pills

I've missed up my birth control this is my third month on them. I started my third pack kinda late I started it after midnight the day I was suppose to start then I did the same the next day. At the end of week one I missed and at the beginning of week two I missed one. I didn't double up since taking one birth control makes me sick sometimes. So is there a chance I've caused my self to be unprotected this month?
