Survivors Benefits?

My husband died April 2014 at the age of 27. I was his first and only spouse. He was my first and only spouse. We had one child, she was born October 2014, about 6 months after my husband's death. My husband was employed off and on before he died and I do not know how many credits he earned. There is no issue of disability, although I was not able to work during my pregnancy due to a pregnancy-related medical condition. I am not currently employed and our 1 month old newborn has been in the NICU since birth. Where do I even start?
