Baby weight gain..😭

Ashley
So I'm at week 21 and I gained 15lbs on the dot! Was looking online, and I am to have only gained 13.5 for the max at this week. My doctor hasn't said anything about my weight, just something I found online..am I putting too much pressure on myself and should I just chill, or should I be more self aware and really watch it the next few weeks? First timer over here!
