i took a pregnancy test on dec 4th and 5th - neg and neg. I missed 4 BC pills in november. I had completely unprotected sex nov 13, 16, and dec 3. This week, I missed sunday's pill and doubled up monday. yesterday, i had some light spotting, but only when wiping. i also had a bit of the same spotting today - it's light to dark brown in color.
help? i'm beyond afraid that this is implantation bleeding. i can't afford a pregnancy test until tomorrow, but even so, wouldn't a pregnancy test be inaccurate until dec 22?
