Mommy groups?

Gabrielle • Married my best friend 9-20-14 & mommy to a beautiful little girl ❤️
I'll be almost 24 when I have my daughter and become a first time mother, I know that it is still considered young and I can definitely see this with relationships with close friends who aren't mothers have grown very distant. How does someone go about finding other moms? Or mommy groups? It would be so nice to find that support and friendship just not sure how other come about finding it? Thanks :)
