I have been using Trivora birth control for over two years now and I would never consider switching brands.  Last year I tried to switch to Target pharmacy for a $10 gift card but they changed the brand and told me it was the same thing and that Trivora was no longer being made, but it messed with my emotions like you wouldn't believe, it was horrible, so I called up Fry's pharmacy and they happily put me back onto Trivora.  This birthcontrol is easy to take, and if you forget to take one until an hour later, you don't have to worry about spotting because it takes a week of missed times to happen...
