I'm 8 weeks and 4 days

Call your doctor! He/she can give you prescription to help. 

I was you 2 days ago and went to see my doctor.  She gave me a list of things I could do including brewing my own tea with fresh mint, ginger, lemon, and honey.  She also suggested sea bands.  I found some plastic ones from a different company and while I am still nauseaus in the morning I've been able to keep most everything down.  I only threw up once yesterday which is remarkable for me.

I'm already in medicine for it it's not working
