I don’t know if it’s an Urban Legend, but I’ve heard that it can take a woman’s body two years to get back to normal after going off the Pill. So if you’ve ever been on the Pill, you don’t need to stress about something being wrong for another year and a half.
While I can understand that you want a baby and you want it now, and that you don’t understand why it hasn’t happened yet, I hope you don’t stress too much about it. Once the baby is born, it will be with you for the rest of your life. There’s no need to hurry a lifetime commitment, is there? Enjoy this special time with your husband - you’ll never be this young and alone again.
