Need middle names

So tomorrow I turn 19 weeks and fine out if were having a boy or girl 😊 but we can't seem to come to an agreement on middle names. If we have a boy 👦we chose Mekhi as a first name and have come up with Jamal as an option for a middle name but just not sure. If it's a girl 👧we can't even decide on the first name lol. We like Trinity and Harley but can't get a middle name for either. Please help 🤔🤔
