Fourth pregnancy, baby number 3. I'm about 7/8 weeks pregnant and I'm constantly tired. My get up and go has got up and gone! I know I'm not helping myself, as thus week I've just given in to the lazy but I'm back to work tomorrow and I need to wake up! I wasn't this tired with previous pregnancies, but I know I know have kids to deal with. I'm trying to eat little and often to combat the nausea but I just feel like hibernating! Any great tried and tested ways to help pep me up?
