Pregnant ?'s: Irregular bleeding can arise from implantation, or from causes not related to pregnancy. Wait a week, and if no menstrual period occurs, obtain a serum HCG test to be certain. If the test is negative, ask your gyn physician about a hysterosalpingogram (HSG) , which can determine if your tubes are open, the most common cause of infertility.
