How to take my BC pill?

So, I missed my pill on Saturday, and Sunday. The saturday pill was the last of week 2 & the sunday pill is the beginning of week three. This is my first pack. It's monday. Do I go ahead and take the monday one and forget about the saturday and sunday ones? or should i just take both sunday & monday pills? Yes, I'm already aware that I may have a chance of pregnancy since I had unprotected sex on Saturday whereas he came in me and i forgot to take the pill on Saturday and Sunday, due to my neglectness.  I just want to continue taking it so i don't worry about it.
