Bloodwork Back

OK, so they have determined that I am anemic. Joy. One one hand, I didn't want something to be 'wrong' because...well..that's obvious...but on the other hand, I'm glad something was wrong so that maybe it can get fixed. I'm soooo tired of being sooooo tired, not motivated, and dizzy. So they have started me on iron supplements for the mean time until they talk further with my surgeon....then they mentioned maybe doing B12 shots instead. So, we will see. So, is true if you have a rough pregnancy that once the baby is here, it will be a breeze? Lie to me...tell me it's true :)
