I called off my wedding, then got pregnant by my new boyfriend of 2 month, how should i tell my family?

[e_fores]

I broke off my engagement to a guy I had been with for 4 years because although we didn't have a ton of problems I was unhappy and knew that he wasn't my soul mate. After moving out I met this wonderful man who was so much like me and fulfilled every little thing that I had ever wanted! He's 34 and I'm 21, and in the beginning I was nervous about telling my family about our relationship for just that reason, and so I never did. Now I just found out that I'm pregnant and so on top of telling my family about our relationship I also have to tell them I'm having his child. He and I are both totally ok with the situation, but I'm just wondering if anyone has any advice on how to tell my family about this extremely unique situation!
I should add that my family did know that I broke off my engagement, they just didn't know about the new relationship.
