Baby shower etiquette?

First timer here. I need some info, because I have practically no experience with this! First question: do I throw my own baby shower, or does someone else throw it for me? If someone else does it, do I wait until someone offers or do I ask someone to throw it??

I’m 23 weeks and we now live 4 hours from family, who would probably throw a shower, I assume, if we still lived there where most everybody is. No one has mentioned anything, so as far as I know, no one is throwing one for us. In our new area, where we’ve been since end of January, we have made some good friends in our church and such, but no one there has said anything either, so I’m assuming unless someone says something, they aren’t planning to throw one?

I think a shower would be extremely helpful both financially and also from the benefit of people enlightening us to stuff we never would have known we needed, so I really hope to have one! I’m growing antsy, though, especially just finding out that one of my sisters in law is throwing a shower for our other sister in law who’s due one day after I am, but she hasn’t said anything about throwing me one. She is closer to her than me, though. But it just made me feel a little sad like no one has thought of one for me? Should I feel like that? Should something be in the works already? Do I initiate things? I have no idea and I would appreciate respectful insights into how all this generally works! Thank you in advance for any input!
