Advice please!

I am a little over 6 weeks, and I am having such a hard time eating. I can barely get out of bed my stomach hurts so bad. All I've been able to get down is soup. My boyfriend just went out to get me nauseous medicine that the doctor approved. This has been going on for three days and I am very worried. Any advice on what to do or what will help? I can't not be eating.
