Baby shower..?๐ŸŽ‰๐ŸŽˆ๐Ÿผ

So I am 9w4d pregnant and the few close people that I've told have already starting talking about the baby shower. I'm so confused! I've only been to a few baby showers before I was pregnant and I wasn't really a fan of them nor was I involved in any of the dorky games mostly because I was intimidated by them. My questions are: when exactly do you plan the baby shower and how far along do I have to be to have a baby shower?ย
