Paleo while pregnant

Any mamas to be eat paleo, or primal? I’m just curious as I’ve done it before, and loved how I felt it was just so hard to stick to. I feel like it’s gonna be even harder for me while pregnant cause I don’t get to have alcohol anymore so sugar is my treat Haha. Anyways, I’m asking cause I know my sugar intake has been very high, and I have my gestational diabetes test in a few weeks! I’m 22 weeks, I haven’t gained too much weight yet but I’m exhausted all the time, and wondering if eating much healthier can help my energy levels😫😴🥗🍅🌶🍒🥑🥦
