First period since stopping the pill

Ni
So I stopped taking birth control last year and I had a period roughly 5 days later. My circumstances changed and so after 4 months I had to take birth control again. 
Now, I am able to stop again and try for a baby. I stopped my birth control 2 weeks ago today and still no period... starting to get concerned. Any thoughts? How long did you take to start a period first time?
