I want to be pregnant so bad!

My husband and I have been towgether for almost two years and have been marrried a month today. We have wanted a child of our own sense the beginning. I have a 4 year old son. I'm just feeling really down today cuz I want to be pregnant so bad. I'm supposed to start my period today or tomorrow and I'm praying that I am but if I'm not I will be upset and we will just have to try again next month. But I don't wanna wait!!!!!
