With all of my pregnancies my hair changed. The curls usually got tighter when I was pregnant and loser again afterwards. But becasue I've been doing CG for a long time I've noticed my curls are tighter then I thought. I chop off a bunch before I have the baby because if you have a lot of long hair it can be heavy and cause you hair to break more and fall out more after having the baby (or so I've read).
