Most likely no: Home pregnancy tests are very accurate when done according to directions. Most likely you are adjusting to the hormones in your new pill. If your symptoms don't improve in a week or two you can retest for pregnancy for reassurance.

Unlikely: Sometimes birth control pills cause pregnancy-like symptoms: nausea, breast tenderness, mood changes, especially in the first 1-3 months. If a pregnancy test was negative, i'd suggest you continue taking it (be sure you're not missing any pills) and see if your period comes when it's supposed to come.
