Hi ladies,
I am 16 weeks 4 days and I am still throwing up constantly. I mean probably twice every hour or more. I've been throwing up so much I can't keep anything down. Yesterday I threw up a little bit of blood. I'm extremely shakey, exhausted, and I don't know what to do. I've been trying to take my prescription from my doctor but I throw it up. Do I need to go in? I'm getting nervous. Any advice? Please
