PLEASE ANSWER

I just had a beautiful baby girl and I am so not ready for another baby.. We are super careful we use condoms and he still pulls out with a condom on and will continue to do so when I start my birth control, I wanted to take this birth control mainly for ance, even though my acne isn't severe at all. Anyways my question is I have the Sunday start pack and it says to take the Sunday after my next period. Well in on my period now and I end Sunday, do I need to take it this Sunday if I am still on my period or wait till next week?? Please please answer.
