Im pregnant and i threw up yellow stuff and then i threw up dark green stuff what is it ? im scared whst should i do?

Pregnancy Changes: "morning sickness" is, of course, very common in pregnancy. If the stomach is empty of food, you may produce a greenish, bile colored vomitus. As long as you don't experience persistent vomiting with dehydration, it should subside by the 20th week. Read this: http://americanpregnancy.Org/pregnancycomplications/hyperemesisgravidarum.Html to make sure you are not experiencing severe hyperemesis.

Meds: You may need some anti nausea meds. Your OB can prescribe some for you. The yellow and green are probably bile. If you can't stop the emesis, you could develop esophagitis. See your OB for some guidance.
