Hi Rainbowz,
Good for you for using birth control. You made a very responsible choice and have maturely followed through with the directions according to the website http://www.orthoevra.com/question-about-patch-how-patch-work.html
If I understand the site, you should be properly covered as far as your birth control goes, with the obvious disclaimer that no method is 100% guaranteed.
I think the symptoms that you are feeling could be due to the fact that your body is adjusting to the birth control, keep in mind that you are now absorbing extra hormones that are changing the way your body cycles and behaves. Swollen breasts and nausea are natural reactions to such change in hormone levels.
Try to keep your salt intake low to reduce your bloating and nibble on crackers to help with the queasiness.
It isn't likely that you are pregnant, so try to relax and wait for your period. In the mean time, it may be a good idea for you to insist on the use of condoms to avoid STIs and also as a back up while you get the hang of the patch.
