Baby shower

Jennifer
To my November mamas. I need some advice I have people ask me what my shower is I don't know when and I don't know how to ask if somebody's going to throw me one to let the people know. Do I have to ask or do I just have to assume somebody's going to do it. And if I do ask is it going to make me sound greedy? Who should throw me one? My sister-in-law said she will help but she's not going to throw it for me
