Pregnancy and growth plates

[Guest guest]

Since I'm trying for baby #2 I went to my ob-gyn and she was

surprised to find that my growth plates have not closed. They are not

open all that much and would only give me an inch or 2 (wich they

don't seem to want to give anyway) but she told me that another

pregnancy might put too much strain on them since they are not closed

and that could be the reason I'm having such hip and knee problems

now. Has anyone had this problem? I always thought growth plates

closed sometime in the late teens but I'm 29. Could this be an RSS

trait?
