. . . .I had trouble sleeping, although I was exhausted. Yesterday the symptoms seemed to completely disappear. Boobs have remained large but are not tender at all, I feel a little nauseous at times and completely put off by my normal food, sense of smell is still very strong. I am just a little concerned as they say this is one of the first signs of a miscarage. Am i right to be concerned? or have I just been reading too many books???
