I posted a question a few days ago stating I was sure that I wasnt pregnant. Now I'm not so sure. My breasts hurt, I have MAJOR bad cramps, i've had diarea, threw up a few days ago, and at work the other day just smelling some of the stuff I normally would eat in a heartbeat made me wanna gag. I'm on the pill, but I just switched a few months ago, its the new pill where you dont get a period. Lybrel. Could these be side effects, stress from home & work, or could it be that I'm pregnant?
