PMS on mini pill

Hey I just started birth control, I’m on my 16th - 17th day of taking it, so my gynecologist said when The first box finishes I’m going to get my period for the week that I don’t take it ( it’s next week).

I’m having cramps and my breast are sore.

Is that normal? Is it normal to have PMS while on the mini pill??

Pls HELP GIRLS I need youuuu😩🙏❤️
