Feeling exausted :-/

Nicole • Firefighter Wife, Mommy, Paramedic!

So this is my 2nd pregnancy and I am BEYOND tired! I never felt like this with my first pregnancy. I take all my vitamins, take extra iron and extra b12 to see if that helps and nothing. Is this normal? What else could I take? Should I request blood work? I can barely stay awake during the day at work and I work in a level one trauma center so I have to always be on my toes....any advice is appreciated!

Also I am 8 weeks today :-)
