period late :/

i’ve been on birth control for about 3 years now and i’ve never missed a pill, always taken it at the same time and been super consistent. when my boyfriend and i have sex we always use a condom when he knows he’s going to finish. but every february for the past 3 years i always miss a period. this year the same thing has happened, i got it the first week of january and i haven’t had my period all of february. should i be worried? i have no period symptoms or pregnancy symptoms... could i be pregnant even with the birth control and protection?
