Nausea & vomiting every day last week, on the same hour, 1 week late. pregnant?

Possibly: Nausea and vomiting in pregnancy tends to be episodic for some, often elicited by such routine activities as brushing your teeth. It is unlikely a "bug" would cause this type of nausea although there are a number of other causes. If you are a week late a pregnant test should be fairly accurate.

Possibly: Take a home pregnancy test. Those things have actually become pretty accurate, especially at the point where you are one week late. Make sure and test your first morning urine for added accuracy.
