Boobs growing during pregnancy

As

I noticed at 7 weeks my boobs started looking fuller, now at 9 weeks I’m poking out the top of my 32D bra cups! I ordered a few new bras a cup size or two larger, since they were on sale at VS.

Are my boobs going to grow the entire pregnancy, or just the first trimester? I’m so scared I will be gigantically top heavy 😭 What has been your experience??
