Birth Control 101? Junel Fe 1/20?

Hi so my mom would murder me if she found out i was in the pill (or just having sex in general) so I can’t really talk to her about this but long story short, me and my boyfriend have been having sex with a condom ofc but we just wanted to be extra safe and get me on the pill so since he knows my mom would murder me we ordered from the pill club and he’s paying for it and it’s arriving to his house since his mom wouldn’t care. anyway i was given Junel Fe 1/20, and i just want to know if any of you have taken it and how it’s gone for you? also I accidentally pressed skip period but i don’t want that can i still get my period if i’m on it? or just general breakdown of it Thank you!
