I am 8 weeks into my first pregnancy, and have been experiencing a lot of "morning sickness." Yet, I am throwing up at all times of the day. In fact, yesterday there was blood in my throw up. I would say it was enough to fill 1/4-1/2 maximum of a dixie cup. Is this normal? Should I seek a physician as soon as possible? As well, since the incident, I have been experiencing minor headaches throughout the day, and sometimes blurred vision.
