Needing friends? How do I make them?

Okay, so this is kinda embrassing but I have absolutely have no friends besides family and boyfriend. I recently had a baby 6 months ago and it's not like I can just go to the club or something like thaf, that people my age do (I'm 21). I'm just really would like to have a couple of friends around my age group... How do I go about making friends now? It's not like I just go up to some girl and ask her what's she's doing tonight? Lol All my high school friends left for college so I'm stuck in my state (NC) where it's not a lot to do.
