I am wondering if I am pregnant.  I started birth control pills in October, and I followed the instructions and waited 7 days to have "unprotected" sex.  I missed a day once, but took the pill the next day.  I was not great at taking them at the same time... I would take them anywhere between 6-11pm.  several missed my period for the firsit time ever.  I have had lots of symptoms of pregnancy, but these can also be side effect from the pill and or pms.  I have also had a few preg tests, all negative.  

I guess I am just wondering what the chances are that I am pregnant? Is it possible to get pregnant on birth control?  Is it possible to have false negative results?  I would be aprox 6 weeks tomorrow.  

 

Or is it all in my head?
