Morning sickness

Shelby • We are TTC baby #1. Rainbow dust to everyone!
I go in tomorrow for my first appointment. I am very nervous! I had a blighted ovam pregnancy in October/ November and we've been trying for our rainbow baby ever since. I will be 7 weeks tomorrow. I've been having horrible morning sickness every day all day long for the past week. I haven't actually threw up yet but I've been dry heaving every day. Any suggestions to ease this? I can eat but I'll get halfway through and have to pause because I'm about to get sick. I drink ginger ale and that  helps.
