Pregnancy weight gain 21 weeks 1 day

A❤️C

I just checked my weight at work and it says I've gained 10 lbs 🙄🙄🙄

But just a week in a half ago I was weighed at my doctors and this would mean I gained 5 pounds in a week in half!! Is that normal??

The baby is also measuring 1 week ahead at 22weeks 2 days (not sure if they are gonna change due date or not)

I'm just worried about gaining to much to fast. I had barely gained anything before . My sister gained 60 pounds in her pregnancy and I'm trying to stay within a healthy weight gain.
