Morning sickness?

E has been getting really sick lately. Morning sickness is really all day sickness, and she has tried everything people have suggested--saltine crackers, ginger ale, a nausea wrist band...everything you name it, we've tried it but none of it has helped. We hope this doesn't go past the the first trimester but I'm sure E wants the nausea to be over now. We are at 7 weeks, amazing how time flies.
