stopped growing!

Between weeks 18 and 22 I gained like 10 pounds very rapidly and I freaked out that I was gaining so fast but now I'm 25+4 and haven't gained anything since. I don't feel like I look much bigger than I did 3 weeks ago and I haven't gained anything since 22 weeks. They say a pound a week is normal 2nd/3rd trimester but curious how you ladies gained? Was it gradual or did you notice at certain times you gained a lot at once?
