I am taking birth control and I have been for about 5-6 months. This last month I didn't have a period when I was supposed to. I have never had irregular periods especially with being on BC. I have taken 2 digital tests and they said negative. Its been a week after my missed period and I still haven't had one. I have been randomly dizzy, and tired this last 3- 4 days. I cannot even smoke a whole ciggy without getting sick feeling and gagging. That's not normal either. Let me know what you all think.. Thanks:-)

I know you know this, but I feel its worth saying: Smoking while on birth control isn't good. Smoking period isn't good.

It might be to soon for a test to tell you that you are pregnant, but not your body. Or it could be something else. If your period does not arrive in another week, you should visit the doctor.
