Kayla
Hello ladies I am 10 weeks pregnant with horrible morning sickness. I basically throw up everything I eat including water. I can eat dry toast bread but if I tried to eat for lunch I throw it up. I can do trail mix but I'm so starving I can drink Powerade zero and sometimes hold down a subway sandwich. Did anything help you guys I even started getting like a discoloration around my eyes like my eyelid is dark and the actual eye please help
