Switching from IUD to Pill

Tarra
So I just got my copper IUD removed because it was hanging out in my cervix instead of where it should be. This was obviously a little painful. My OB/GYN told me to take my first birth control pill that night. I've taken them every night at the same time. Should I be worried that I am now almost a week late? Or should I just account it to switching to the pill? PS. Do your boobs ever stop hurting after starting the pill?
