Maid of Honor confusion

So I’m getting married in July of 2020 (this year) and my fiancé and I decided to do the wedding on the 31st, it’s a Friday and far enough from his birthday (it’s on the 19th) that we felt comfortable putting it there... until my MOH and one of my bridesmaids said that they have stuff going on that weekend. And although my fiancé and I were hesitant to, we agreed to put it on the 24th, Pioneer Day, also one of my grandfather’s death anniversary. But whatever, we pushed it. And then my MOH mentioned that if we were to do our wedding on a weekend, to keep in mind that she wouldn’t be able to go since she works. She works at a hospital as a graveyard shift cleaning tech. I told her that I’ll think about it. I talked with my fiancé, and we’re still going to have an evening wedding since he is a business owner and he’d like to work at least a little bit. We’re not going past ten o clock at our wedding, meaning my MOH has about five months to ask her work if she can take a few hours off. Not to mention she said nothing about planning a bridal shower or bachelorette part or anything, one of my other bridesmaids actually started planning my bachelorette party immediately. What should I do? I don’t want to be a bridezilla but I don’t want to be a pushover either. Help?
