Thank you for your question. Your obstetrician can prescribe medication to reduce the vomiting. Its important to go to the hospital before you get too dehydrated because it is much harder to correct the longer you leave it. You can try natural remedies like ginger and clove. But these tend to work better for nausea than for vomiting if used early. Please don't self medicate at lots of medicines are not safe in pregnancy. best wishes
