Birth Control - Help!!

Jordan

So I take Volnea birth control and there’s three pills. Three weeks off white ones, two days of green ones, and then five days of yellow ones.

I know for sure I’m supposed to get my period on the yellow pill days, but I just can’t remember if I get them on the green pill day.

Every month I’ve been on it, I’ve forgotten to take one or two, and gotten my period. This month is the first month I’ve take every single pill on the day I’m supposed to. Idk if that change’s something or what. I just took the second green pill. Im worried, and confused. I can’t go to my mom, she’ll just assume I’m pregnant
