Nervous about telling our family

We were married 3 months ago and just found out two weeks ago we are pregnant with our first! We currently live in my godparents basement apartment. We plan on purchasing our first house in September, I'm due in February. We moved in with family for a few months to offset the cost of our wedding. However I'm nervous they will react negatively to the baby news... Since we're still living in their basement... How do we approach this?
