Negative test

Odie

So I took a clear blue brand test and it seems to be a strong negative (picture below) but I had a question with false negatives, I’m on birth control pills and last month I was late a few days one day by 6 hours and 2 days by 2. I also had sex and he finished inside me, I’m late 2 days as of today, is it still possible? My last period was November 2nd and lasted 5 days. Any advice?
