Did you have unprotected sex? If so, you can try another pregnancy test. But periods really CAN just be late. Stress, changes in routine, lack of sleep, illness, weight gain or loss all can cause periods to be late. And you may also be about to start with the bloating. So, IF you had unprotected sex, take another pregnancy test. If it is negative, then keep waiting. If it gets to the 3 month mark and no period, then make an appointment to see your doctor to discuss. good luck
