Is it normal that it takes so long to get your period back after stopping the pill?

Hello, I stopped taking my contraceptive pill permanently at the beginning of December 2022. I then had my period on December 18-19 and 20 and nothing since these dates. It is now February 23, so I am 38 days late. Of course I did pregnancy tests which were negative. I know it may take a while before I am regular on my own without the pill. But I'm worried that I haven't had a period since.
