Thanks for your query,
You have not given any history regarding sexual life. Are there are any chances of pregnancy? If yes , then you should do a home pregnancy test at earliest to exclude pregnancy.
Your signs and symptoms are suggestive of early pregnancy but they are not always specific. If there is no chance of pregnancy then you will be given progesterone
to cause withdrawl bleeding by your doctor .
Best of luck and take care..
Hope it helos you..
