So I'm 11+3 and have been awake since 1am. (Only 1.5 hours in total sleep). I've struggled with sleep over last week which results in me being shakey and exhausted by 2pm, nog exactly functional at work and now really down in my hours. I haven't told work about pregnancy but really need time off. I really can't face going in today, but not sure what to tell my boss (who I can't tell the truth to as she keeps no confidence)?
