Aiyoh at 22 weeks baby usually around 430-500 grams je, macam size of papaya! Tapi honestly setiap baby lain-lain, some slower, some faster growth, so long as doctor says okay during scan, don't need to worry sangat. Mine dekat that stage okay je, then later bila 28-30 weeks baru macam consistent growth pattern nampak. Kalau nak reassurance boleh tanya doctor during your next checkup, they can measure via ultrasound, that's the most accurate way.
