Okay ladies I need help!

So I went to a women’s doctor today for birth control I’m planning on getting the Implant in my arm but until then they gave me the pills and I’m not sure if I should take them now but the instructions said to take it on the first day of my cycle but, by the time my period gets here, my implant will already be delivered, so not sure if it’s okay for me to start taking them now or what. Also all the pills are blue expect two one is white and one is brown what are they for?

Here are pictures too as well
