I was so pleased to see my little one on the scan yesterday and to learn everything was ok, but now my happiness is tinged becuase I feel so ill. I have a constant unbearable headache which I've had since yesterday lunch time, I feel sick almost to the point of being sick, and I have no energy whatsoever. All I've done since yesterday afernoon is sleep. Does this sound normal or could I be coming down with something? Also can I take a couple of normal strength paracetamol just to take the edge off the headache?
