Pregnant again

Tabitha
A little about me. I'm 24 years old and gave birth to a beautiful baby girl November 25th 2016. Today I found out I was pregnant again. I'm excited but scared because my daughter was my first child so I'm a new mom and now I'm going to be a mother again so soon and they're going to be so close in age. Has any other moms been through anything similar and had any complications having a baby so soon after giving birth. I don't plan on telling anyone until I at least find out the gender so this is me and the baby fathers little secret until then. He is the father to both of my children by the way. He and I have been together four years now. Any advice anyone can give or if you can share your experience please feel free to comment.
