I'm recently pregnant and have been feeling tired, fullness in my head, dizziness and loss of appetite?

Can see one's Dr.: One's primary care doctor can help with such symptoms. Sometimes the symptoms are due to a new illness, such as a cold or other viral infection. Sometimes the symptoms are due to being pregnant, with its hormonal and emotional changes. Of course, symptoms can be a combination of both factors. One's doctor can help figure things out.
