The first section ("Yesterday, all my troubles seemed so far away ...") opens with an F chord (the 3rd of the chord is omitted), then moving to Em7 before proceeding to A7 and then to D-minor. In this sense, the opening chord is a decoy; as musicologist Alan Pollack points out, the home key (F-major) has little time to establish itself before "heading towards the relative D-minor". He points out that this diversion is a compositional device commonly used by Lennon and McCartney, which he describes as "deferred gratification".
