Could I be pregnant?

I took a plan b on september 12th which was 3 days after I just got off my period. About a week later the bleeding that follows with the pill occurred so i wasn't worrying.And it stopped on september 22nd. well since then i have had sex 5 times and all have been protected. No tears seemed to be in condoms but i still haven't gotten my period and i am worried. I heard that plan b can make the 2nd period after taking it late but i have been getting cramps for the last couple of days with no period and i read online that that is an early sign of pregnancy. but i know it can also mean i am about to start 😭 has anyone experienced anything similar?
