Same here with the second pregnancy. Didn't show at all until 6 months with my first son, then about 5 with the second. The third? I looked like I was pregnant with twins about 15 minutes after I peed on the stick. I was as big as a barge and super duper fast.
I don't know why...maybe because all the parts have already been stretched out. I do believe you carry boys and girls differently, though. My first two were boys and I carried them all out front. My third was a girl and I swear I carried her all over my body. I think I even had pregnancy weight in the back of my neck. My boobs mutated to an abnormal and unflattering size and sadly they never went back to remotely close to normal. I am seriously considering trading them in....
