Baby weight gain each week

Nimz 🌈

Is it normal for the baby’s weight gain to fluctuate each week? My baby’s weight was increasing almost 200 g each week but last week only 50 g . But within the normal range according to weeks. I’m 31 weeks and he is weighing 1.7 kg. I’m just concerned why only 50 g this week is this a sign growth is stunting?
