Normal after plan b?

I’ve taken plan b in the past, but never really had side effects. Period usually began 5-7 days later. 9 days ago, the condom broke and I took plan b. I’ve had some light cramping, tightness in the lower abdomen, moodiness, bloating, and gassy. Still no period, but it’s not due for a few weeks. Are these side effects people have experienced or should I be worried it didn’t take?
