No Sign of AF

Amanda • Wife, Mommy & Bonus Mommy
So AF is a week late as of today. And I've tested three times and they were negative. What would you guys suggest as my next step?
I am TTC, 21 and this would be my first! I stopped taking my pill on June 14 of this year and have had 2 normal, on-time periods after the first one that I had from stopping the pill.  
Thanks for any feedback! :)
