weight gain at 22 weeks

i didn’t weigh myself super often before i got pregnant but my normal weight was around 200-210. last i checked before i found out i was pregnant (around early june) i was 208.. september 13 was the next time i was weighed in the er i was 194.4 (14 weeks.) well i weighed myself again a week ago and no change. finally i weigh myself today and i’m 197😭 it’s such a small amount but is 3 pounds in a week normal? maybe baby grew a little pretty quickly? i’ve been very hungry but i eat pretty healthy so i’m not worried about what i’m eating. i’m trying to stay under 20-25 pounds 🙄
