Late but not pregnant 😡

Hey ladies. I went off birth control last month and had the withdraw bleeding. Now I’m waiting for my first real post ovulation period. As of a few days ago, I’m officially late. I keep testing but I’m still not pregnant and no period. This is driving me INSANE. I mean, I’m only a few days late but I’m used to the pill keeping me on a strict time table. How do you ladies who have been doing this for months on end keep it together?
