Detailed Answer:
Hi there.
I welcome you to Ask A Doctor service.
I need to know some more information before advising you about the best treatment options.

Please send me the following information:

1. Your age?
2. Date of your last menstrual period?
3. If you have missed your period then have you done a pregnancy test on morning's first sample of urine?
4. Have you done any sonography?
5. Are you taking any medication?

All the symptoms that you are describing can be due to early pregnancy.
Please, try to have small and frequent meals.
Avoid a gap of more than 3 hours between two meals.

Please feel free to communicate with me further...

Thanks
Dr. Purushottam Neurgaonkar
