Morning sickness?

Since yesterday morning I’ve been throwing everything up and feeling nauseous. I feel like this is the flu and not morning sickness. I can’t keep any fluids down or eat anything. I’ve tried medicine that my nurse suggested for morning sickness and nauseous. I just can’t even sit up in my bed without throwing up. Is this normal? I’m 19 and the pregnancy was unexpected.

Update: today was much better. I didn’t throw up through the night. The medicine is working (since I didn’t throw it up). I did call the doctor and she told me to take Vitamin B6 and Unisom. I didn’t do much today but the vomiting has stopped I still feel a little nauseous but after those 2 hard days it feels like nothing. Thank you everyone for your comments. I seriously thought I had the flu. Thank you.
