Belly not growing

I'm currently almost 23 weeks pregnant. This is my second baby. I've been showing since 12 weeks (with bloat of course) and it seems like my stomach has been growing a lot since then, but since 20 weeks I haven't noticed any growth. I feel like I still look the same, sometimes feel like I look smaller. With my first I could tell there was growth every week. Doctor didn't say anything about my size when she measured yesterday. It's just weird to me. Anyone experienced this?
