Third trimester/rapid weight gain.

So, I had my last appointment 3 weeks ago and I was weighing in at 183, which means total weight gain that far had been 10 pounds. I was 25 weeks at the time.

I’m now 28 weeks and I weighed in this morning on my home scale and it says I’ve gained 5.5 pounds since then. Which puts me at 187.5

I feel like that’s a huge jump. That’s more than half of what I gained in the first 25 weeks...I eat healthy, and I exercise regularly.. what could this be from????
