Seasonique questions?

It is a good thing that you aren't having breakthrough bleeding, and it doesn't happen to everyone. This usually happens when your hormone levels are shifting. If you are good about taking your pill every day at the same time, then you are less likely to have breakthrough bleeding and your pill is more effective than if you were missing doses. It sounds like you are ok, but if you are concerned about a possible pregnancy you can test right now with an at home pregnancy test. Certain medications, like antibiotics and anticonvulsants, can make birth control less effective so if you were taking any of these you will definitely want to test.
