Lo loestrin fe

I started my new BC last Thursday, the first day of my period. The patient information says, "Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days if she starts taking Lo Loestrin Fe other than on the first day of her menstrual cycle." I'm assuming that means after tomorrow (Friday, 8 days) I'm good to go & that we don't have to use condoms or pull out or anything?
P.s. I hate that I still don't necessarily trust birth control!!!!!! Lol
