Hey I know this sounds kinda stupid but how much sleep am I supposed to be having,I am 16 weeks pregnant and I am dead on my feet every day struggling to get up in the mornings,then tierd all day plus I have a 2 year old so I'm pretty tierd out running after her most days but I seem to be unbelievably tierd and I was never like this with my last pregnancy I don't know what wrong with me
