Im a expert at worrying =/

I used a condom when I lost my virginity on May 21 & I'm not on birth control pills ... no breaks or tears and he didn't even cum inside of me but I still worry of pregnancy cause I'm a scardie cat at life plzz tell me if I'm okay?!? Also i started my period the morning after on May 22. & now its the middle of my next cycle and experiencing tiny bit of spotting but it could be caused from masturbation cause my bf showed me how ro do that last night ... lol im so lost... but will i be okay im sorry for my ignorance in this topic.
