Your not out of the game yet, it's still a little early. I didn't pick up faint lines till day 8 or 9. On the nausea, I would call the dr back and explain how severe it really is and ask for zofran. It's safe to take while pregnant and you can't continue to suffer like that. You have to eat to be healthy. Ginger is a antiemetic/ motion sickness supplement but it takes days for that to kick in. They tell people who get sea sick to start taking it three days in advance before they go out in the boat. I hope you get some relief soon and don't loose hope yet, you still have time. Best wishes!
