No period while taking placebo pills

Ummm so I only have 4 days of the non active pills and I felt like some very light cramps like my period/withdrawal bleed was gonna come but it never did. I just started my new pack of pills today. I guess I’m not pregnant. It’s just a skipped period or something. I never missed a period while on the pill although I have noticed they gotten very lite. 🤷🏻‍♀️
