This is my second pregnancy and I feel like shite. The sickness has already started, my whole body aches, I'm dizzy, have a head ache and am freezing cold (I normally get the chills when I'm sick when not pg anyway). Ds is 17 months and hard work, but even taking that into account I don't remember feeling like I'd been hit by a train at this stage last time. Are all these symptoms normal or something I need to get checked out?
