Stopped Pill Waiting For Period

​I stopped the pill on Jan 5th. I've been waitig since then for a period and it hasn't happened. I am Definitley not pregnant (as I had a blood test to confirm).
​How long was it for you to get a period after stopping the pill? I was on it for 15yrs an never had a regular cycle before I went on it.
​Any advice/comments are welcome!
