hi im 16 years old and I suspect I'm pregnant, I took a test yesterday afternoon and it was negative. My last "period" was 12/02/2014 it last until that night and consisted of only brown spotting and slight pinkish red spotting. I'm on Microgestin Fe 1/20 birth control pills, but had sex around 11/14/2014 using the withdraw method. I'm having multiple symptoms of early pregnancy and I just need to know already if I am pregnant or not. Please help with suggestions if you have any. Thank you.
