I barely slept last night and went back to bed this morning at 8.30 after dh took ds to nursery. I woke up at 11- this is weird for me as I never lie in and feel like a total lazy slattern. I have no energy to do anything, and feel weepy and tired and a bit nauseous. Feel like being pg is getting me down, don't remember feeling like this last time 
Is this normal?
