Packing on the pounds.. early pregnancy?

Okay call me crazy but the past couple days I have gained 3-5 pounds. My schedule hasn’t changed, my diet hasn’t changed or my “exercise” (I get around 20,000 steps in while at work). I’m not too sure what the deal is. I’ve never been pregnant before so I just don’t know 😂

I’m around the point in my cycle where I would have implantation. Could this be the bloat people talk about?? I know I’m probably just fat, I just don’t know what the deal is with my body right now 😂😂
