Need advise

Amber

I finished my period August 21 and stopped BC on August 27. My period was suppose to start last Monday and I’m going on 8 days late. I’ve taken a few test including today and it was negative. I had a day of brown spotting a few days before I was suppose to get my period but that was it. Thinking period was thrown off because of the extra week of the pill but REALLY hopping I’m pregnant. What ya think?
