I am 6 and a half weeks pregnant and so tired I can't get out of bed. I have told my boss (who knows I am pregnant) that I will be in late which he is fine with, but I am wondering if this level of tiredness is my body telling me to rest properly? Could struggling in when this tired harm the baby? Should I take the day off? Is this tiredness a hint that I need to stay lying down or do I just need to pull myself together and drag myself to work? Help - I need to decide! TIA.
