Hello my name is tiffany . My period is suppose to start around the ninth of each month. The beginning of December was my last normal period it was late in January. I have been feeling nausea every night. Does this mean I'm pregnant?

The important question here is have you been having sex?

You had a period late in January? Then it's very unlikely that you are showing pregnancy symptoms this early. If you are pregnant, then you got pregnant in the last few days.

Do a home test if you really think you are pregnant, and then start using contraception.
