My OB wants to see me at 12 weeks, but seeing as you're going away then, I'd probably try and see him before you go. Can't hurt. He can probably give you advise on travelling while pg too.

I'm just over 5 weeks, and have had very little symptoms. The only thing is I'm starting to sleep a lot. I never sleep through the day.. but I'm starting to now. hehe. and I crash pretty early at night now too.
