am i with pregnant??

I’ve had sex a few times recently with protection and he’s pulled out every time before just for even more safety. we have even checked the condoms to make sure they were alright. my period is 3 days late now i don’t know what to do. I’ve had tiny cramps and my face broke out like it usually does right before i’m supposed to get my period. i’ve been more stressed lately and last time i had my period the cycle shifted a little back since school had just started again and my body was adjusting to a new routine. could my cycle just have changed a little bit and the stress making it worse??
