is this normal...? her sacn yesterday suggested all was fine and we saw the baby's heartbeat. all seems healthy enough but i am just worried a bit that my wife is always sick or retching (although holds down fast food and sprite on most occasions). she has gone off water and finds it hard to keep that down. her wristband doesnt seem to work and she has tried ginger and eating small amounts regularly but nothing much stays down. when she saw her gp today she was really off apparently and suggested that many try to use pregnancy as a means of taking time off work! (i am not happy about that). her midwife suggests she try to keep water down but it aint happening. however i have read that this is all a sign for some in the first trimester and that after 12weeks the sickness etc can ease off so is it worth waiting til then...? please help, as the main concern i have is my wife being thirsty (unless this comes with the sickness?)
