Brief Answer:
Need more information...

Detailed Answer:
Hi,

The details you provided is too short and very generic to give you an useful information. Can you elaborate?
Since when are you vomiting?
Do you have stomach pain / loose stools or any other associated complaints?
Are you sick / running fever?
Please confirm your gender?
Assuming you are a female - Is your period regular? When was your last period?

Answers to these questions can help you understand the problem better.

Meanwhile if you persist to have vomiting, you may consider taking an antiemetic agent like tab domstal or cap pan D and see if it helps.

Regards
