I'm 7 weeks today and for the last 3 days I've had morning sickness. I haven't been able to eat because the smell, look and thought makes me vomit. I'm barely able to tolerate small amounts of water. I'm not hungry but extremely thirsty. I'm vomiting at least every 90 minutes, all that is coming up is very dark green bile. When does this become concerning for mine and bubs health?

Hyperemesis Gravidarum | American Pregnancy Association (http://americanpregnancy.org/pregnancycomplications/hyperemesisgravidarum.html) is very common in pregnancy. This is something that you will need to address with your OB/Midwife. In the meantime, eat saltine crackers before getting out of bed, drink ginger ale to assist with the nausea.
