Dear mums, this is my second pregnancy and I'm looking for some reassurance..I had some fleeting nausea in first pregnancy but that was its. I'm really scared since for the past two days I feel so exhausted as if I've been hit by a bus. I haven't showered in 2 days ans have just been in bed. In addition I am nauseous so can't eat. Is this unusual to feel this kind of exhaustion? I've read about mum's having to take naps but I feel this is something else since I literally can't do anything. Please help. X
