Do I need to use additional mechanical contraception after stopping treatment with Sumamed if I take Yasminelle?

Good morning, please hint. From today for the next 6 days I have to take sumamed. Also today I start a seven-day break in yasminelle. Should I start the next pack in a week's time for a few more days, or will taking an antibiotic during the break not affect the subsequent effect of the birth control pills? The leaflet says nothing about the effect of azythromycin on hormonal contraception. And the second question is, after 6 days from the last tablet of sumamedu I will be able to drink alcohol safely (in a reasonable amount)? Thank you in advance for your help
