My Period Is Late Dear Dr. Prager, I'm a college student, with a history of menstrual irregularity. However, a few months ago, I became sexually active and my periods have not only become regular, but even "in synch" with my roommate's (who is on birth control). My question is: I should have gotten my period this coming Wednesday, but I woke up this morning with some discharge. I put in a tampon and changed it once. The flow has been EXTREMELY minimal. In fact, the latest tampon had no blood whatsoever. I'm wondering if I should worry —considering this is also finals time (i.e., stress). But I'm also worried about the possibility of pregnancy considering I haven't started taking the pill yet. I tried to do some research on the web, but figured you might be able to help me out! I'd appreciate it so much. Thanks, Maya --- Dear Maya, With an irregular cycle and no reliable form of birth control you may be pregnant. Take a home pregnancy test or see your healthcare provider. When using a home pregnancy test, you need to read the package information to find out when to use the test as this varies from brand to brand. The synchronization of your cycle with your roommates is not unusual. This is not the problem. Having unprotected sexual intercourse is the problem. If you are sexually active, don't take chances. Practice safer sex by always using a condom—even if you are on the pill—or even better is to abstain and not have sex altogether.
