I am constantly nauseas lately. i still have an appetite but at the same time the thought of food makes me want to throw up. i occasionally throw up.

Pregnancy test: If you had sex since your last period and missed your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. If the results remain negative, you should see a doctor for an evaluation. Wish you good health!
