could I be pregnant?

This is my first post on here... hi guys! So this is my first full month off birth control in 9 years.... on birth control I always started either Wednesday or Thursday morning at the absolute latest.... it's Friday and I still haven't started yet. I took a test the other day before I actually missed and it came back negative. Could I still be pregnant? If I haven't started by Sunday I'm gonna take another one... I know this could be from being off birth control but I was always regular even before I started birth control. I'm being hopeful and HOPING I'm pregnant but also trying not to get my hopes up 😞
