Need help

Okay ladies, I had sex a few weeks back. Used a condom, pulled out and even took plan b to be on the extra safe side. I got an early period from the pill then another a week later. I know I shouldn’t be worrying since I got my period but here I am worrying. Please reassure me I’m not pregnant cuz I’m freaking out thinking I am when I know it’s very hard for me to be since of the protection and the periods. Please and thanks !
