Weight gain/weight loss on nexplanon

I gained a lot of weight in college. I'll be honest. Most of it was all my fault. But I got nexplanon in January and have noticed that it's become a lot easier to gain weight and harder to lose it. So I've decided enough is enough and to start working out, eating clean, all that about a month ago and it's been going really well!. But I just checked the scale for my weekly check in and gained 2 pounds!!! And it wasn't muscle because my measurements haven't changed either :((( I love my nexplanon but this is the only side effect that I'm not excited about...has anyone else had this problem? Have you overcome it without removing it?
