Good day!
I just wanted to ask if it is implantation bleeding or not. I'm supposed to have my period on 09 Dec 2016 but around 9pm of 08 Dec, I drink a glass of coke and after a few minutes I went to the bathroom and saw a blood on my panty for about 4 inches. And I until today, 10 Dec, I have a very light flow. (But my normal period flow is not so heavy as well) However, I am on pills so I'm confused. Please help. Thank you
