Nausea worst in mornings, lingers but not as bad all day. sensitive to smells. tired all the time. gastroenterology tests detect nothing.not pregnant.

Patience is a virtue: It sounds as though things haven't been easy for you lately. This situation can only be handled well by getting back to the basics of office medicine. A comprehensive history and physical exam, along with the testing that fits with your symptoms. There are not going to be any shortcuts here. Talk with a doc who gives you appropriate time and attention. Negative tests are helpful too, have faith.

You're sure - right?: Well, if you are definitely not pregnant this might reflect a situation that creates these common early pregnancy symptoms. I'd suggest a full OBGYN exam to find what is acting in some respects like pregnancy. Hopefully, an OBGYN here will give advice too. But it's worth a good exam to find out. Best!
