OVER A WEEK LATE still nothing

Cherie
So I'm 8 days late with my period and took a test yesterday and still 👎🏼 negative. I was on the bc shot (depo) for about 6 years and I got off o it about a year and a half ago and went straight to the pill. And I stopped taking that about 4-5 months ago. Is there a chance that I can be pregnant and the test are just not showing it yet???! I'm need some input/advice
