Maternity pants help!

So i bought a few pairs and they were so comfy in store. But when i wore them i noticed they slip down so much and i constantly have to pull them up. I know this is because i don’t have a full belly yet, but i am too big to fit into my old jeans. I also find my old jeans super uncomfortable even unbuttoned.

I thought about getting a belly band...have any of you wore a belly band WITH your maternity jeans for the extra support to keep them up? Is that weird? I’m trying every possible avenue here because i find the jeans so dang comfy.
