If your boyfriend withdraws to ejaculate that isnt a 100% effective way to prevent pregnancy because of pre ejaculation. If your really worried take a pregnancy test, thats the only way to know

I would do a pregnancy test like suggested if its negative it could be several different reasons it's delayed for example an ovarian cyst, stress, just starting oral contraceptives, a hormone imbalance. If its negative you should see your doctor or at least call.
