period came early on the pill

so i’ve been on the pill for almost 2 years now and have been sexually active the whole time i’ve been on the pill. this month i took two pills late and my boyfriend and i used the pull out method around that time. my period started a week early (during my last week of active pills) and then when i finished my active pills it ended and now i’m on my placebo pills and i have a bit of spotting but no bleeding anymore. this isnt the first time that my period has come early on the pill after messing up my pills but usually i bleed until i start my new pack but this time that didnt happen and i’m wondering if that is normal or not? this doesn’t sound like pregnancy does it?
