Using of birth control pills

I am currently taking birth control pills for 3 months. My last active pill was on july 13 but I did not take the placebo pill cause I don’t want have my period yet. Instead I take it continously. May i ask if i am still protected if will take 29 active pill? If I’ll have unprotected contact tommorrow will I still be safe? I am planning to take placebo pills on july 21.
