Hi Girls

I am currently 39 weeks and this is my first baby. I am a little scared about the whole birth thing. I am not so much scared of giving birth (ok maybe a little) but more so of what if my waters break and I don't know or what if I get a show and don't realise. I guess my concern is when do I go to the hospital etc. I went to ante natal classe but was greatly dissapointed, I didn't find them informative at all. My doc says you will know.
Any advice greatly appreciated from you girls who have done this before.

Thanks
Jules
