Do placebo tablets count towards a 7-day period in which you should additionally protect yourself after using an antibiotic?

Good evening 🙂 have been using Drovelis oral contraception for 23 days (I used to take Atywie Daily and the placebo pills were omitted and from 22 tab I switched to Drovelis as prescribed by the doctor). I have been taking the antibiotic Augmentin for 7 days because I pulled out the eight. Today I take an antibiotic for the last time. As for the anti I am on the 23rd tablet, tomorrow I take an active and 4 days placebo. My question - is 7 days of additional protection enough after the antibiotic treatment? I mean the time when I will take a placebo or it "counts" in those 7 days that are always mentioned with antibiotics. Thank you in advance for your reply 🙂
