Is this Normal?!

Julie
Ok, so this is baby #3, but before I go on my last pregnant was about 10 years ago....I have severe severe heart burn and I've had this since about week 4 and I'm 6 weeks now. I feel like my insides are burning away! I've also been nauseous and bloated of course but is it normal to be starting all of these symptoms so early and so intense?!?! I feel like with my last pregnancies, my symptoms didn't intensify until after at least week 8! Anybody else going through this?
