I am not completly sure of what kind of BC I take (My parents have been ordered by doctors to keep ALL of my medicines away from me so i just take what my parents hand me) , but i've been taking it for a few months. It's on a low dosage because i've taken BC in the past (before i was sexually active) and it made me throw up. I have been experiencing some side effects and i was wondering if theyre normal since i didnt experience any of them during any of my other cycles. 

ive been bleeding some for the past week (i'm not supposed to have my period for a week), lots of nasuea, but no throwing up, fatigue, constant dizzyness, headaches and fainting. Me and my boyfriend are sexually active, and my best friend is 7 months pregnant and has told me these are symbtoms she had when she first found out she's pregnant.......so i was wondering if there is any way i could be pregnant? I have NOT missed any pills
