Have you taken your pills consistently?

Symptoms could be pregnancy...Why don't you check with a hpt?

The thing about hormonal birth control is this - your body thinks it's pregnant and is tricked into not ovulating so many symptoms of pregnancy are also "side effects" of hormonal birth control. I for one had a month of morning sickness, literally I would wake up every morning and throw up. If I wasn't taking my pill as close to perfect as is humanly possible I would have intrepreted this as a sure fire pregnancy sign. See where i'm going? Having symptoms dosen't necessarily mean you're preg as it would likely mean if you were not on b/c. That being said - there is a very small chance yoiu could be preg even with perfect use (about 1/1000 women will get pg on hormonal b/c) so here's what I think you shoud do. Continue using your path as directed (it will not hurt the developing fetus on the off chance that you are pg) and see if you miss a period on your patch off week. That is the time to get worried - not now.
Best of luck
