I havent received my period and it normally comes around the first week of the month. i am feeling nauseous everyday but there is no way i am pregnant. i have a loss of appetite for a day or two then i am able to eat for 1 day then back to nausea.

If not pregnant...: A doctor can evaluate if nausea symptoms last more than a couple of days. Nausea can be due to many things, such as: stomach virus infection, other viral infection (such as flu), some bacterial infections (such as strep throat), acid reflux (heartburn), gastritis (may be H. pylori), gall bladder or liver disease, certain cancers, kidney diseases, anxiety, depression, medications, etc...
