Birth control and condoms

I use birth control ( pill form) and if i ever am intimate with my partner we use condoms and check them after to make sure they didnt pop, but my period is late by 4 days which is really rare for me, i dont know if stress is the reason for it but i have like really light spotting but thats it, if anyone knows anything that could help cause missing it is stressing me out! Thank you ladiesss!!!
