Get pregnant or wait....

So I just started a relationship about a month in. The guy is absolutely amazing. He has been everything I wanted in a person and partner. we share alot of the same values and goals for a relationship. We both are 30 have great careers, I have a house. Pretty much have our lives in order. We both have baby fever, like you wouldn't believe. I have an appointment monday with the plan to start BC but he wants to try and get pregnant. I want that more than anything but Im scared it is too soon. We need to learn more about one another. I know we'd make great parents because I see how he is with his son and my nieces and nephews. I worry about holding off because it might take time and I might not get pregnant right away either so that gives us some time as well. Before him my baby fever was so bad that I told myself in a year if I didn't find a person I adore and want kids with I will just do it myself with a donor. So what do you think? Wait or just go with it and see what happens?
