I switched pills. How do I mark that here?

Like the title says; I switched my bc. How do I denote it in the app so that it stops asking me if I got my period and doesn't think I'm late? My doctor told me to start my new pack when I would have started my week of placebo pills from my old prescription so I'm skipping my period this month (actually right now) also with this new pill, LoLoestrinFe, I should only be getting it 2-3 days where my cycle was usually 5-7 days on the old one and that's what it's set to on here's
