Im 5 weeks and 5 days pregnant , I been doing good up until I started taking my prescripted prenatal pills.. The bottle did say "may cause discoloration of the urine or feces" but my discharge went from white and creamy, to light light brown and creamy to light pink... my first OB appointment isn't until the 10th ... I have light to no cramps , I just don't know what I should do about it. I'm scared I don't want nothing to happen to my baby.  So could the pills be the reason for all this?
