I was the same as you very curoious about being pregnant etc, I'm now nearly 29 weeks and I have to be truthful and say at first I didn't like it at all, but once I got over the sicky feeling it's truly amazing, like hearing the heartbeat each time, feeling her kicking, getting notions for different foods, it has it ups and downs like everything else. As for sickness and work, it's probably easier if your working it takes your mind off how you feeling, but not everyone gets morning sickness, I knew a girl who didn't have any at all, and there are ways to get over it, some work some don't.
Although I told everyone soon, it wasn't really noticeable until I was about 22 weeks, it depends on the clothes you wear!!!!!
As for the last 2 can't aswer them just yet but I will be going back to work at some point after the baby is born and I've been told that the birth will probably hurt but all that goes away when you hold your baby in your arms.
I really do hope my words help and don't scare you off, I believe in telling it like it is!!!!!!
Let me know how you get on!!!!!
