Nautious for 8 days

I have been nautious for the past 8 days. My last period was lighter than normal, and only 3 days long. It was Dec. 27, 28, 29, 2008. I am on teh Birth control pill, but have unprotected sex with my boyfriend otherwise. I am due for my period on the 24th of January. But I am still freaking out. I often go to the gym, like 3 - 5 days a week, and havent been able to, because the slightest bit of running makes me cringe with nautiousness and feel weak.
Any thoughts?

I know the feeling! I dont know if a shorter period means anything but I know I got sick from a certain pill so if you recently switched brands, this might be why you are experiencing all the symptoms you are going through. Let me know if it happens to be a baby.

Birth control can make you have shorter periods.  They aren't 100% effective so take a test as soon as you miss your period to find out. Good luck!
