Just going from Yasmin to Slynd. Should I skip placebo to not have period or it doesnt matter?

Hi. I have endo and I try with my gyn new meds. I loved that on Yasmin I had no period at all!! I wonder if I should skip placebo on Slynd to not get period? Will I have period If I take placebo etc? I forgot to ask about it. Also thinking If any option is better in endo patients.
