Bridal shower advice very long post

So my FH and I have been together for 3 years and both had established households before we moved in together. I wasn't planning on having a bridal shower. We planned on if anyone gave a cash gift at the wedding to put it in a savings fund to eventually go on a honeymoon. So my FH SIL's sister was just got married and so with all the talk and planning for her events my FMIL kept asking about my bridal shower and what was my mother planning to host. Unfortunately I love my mom but it's not her thing and she never mentioned it. So I was planning on no shower. Then I got thinking that upgrading to some new household items would be nice. My FMIL thought I should mention it to my two bm one who is my FH SIL and other his sister. Both I close with and we get along. Things have come up and no one has had a chance to get together plusI wouldn't want to burden my FSIL since her sister was getting married and she was busy with that. Then one of my friends from back home (my family, MOH, and old friends live 4 hours away) asked about our registry. I said I don't have one she said why not. I said well I'm not having a shower. She was taken back and said she wanted to host one and to make a registry. So FH and I did. I am going away with FMIL and FSIL in two week then weekend after that going home 4 hours away. What should I do. I know my wedding is still 4 months away but problem is I'm an RN and we complete our schedules a few months out. I'm going to be completing my July and August schedule in first week of June. The entire bridal party and that friend from back home will be at my bachelorette party last weekend of June. I feel like they may scheme then but it would be too late for my work. It is extremely hard to get switches. A girl recently got denied her wedding day. Should I casually mention it or let it go. Just not sure. Ant advice appreciated.
