My period has got delayed for 12 days for the first time. Why does it happen?

Hello,

Welcome to icliniq.com.

Before we could determine the exact cause for this prolonged bleeding, I would like to know a little more details about your previous cycles. As you said you always had regular cycles, just wanted to know if your previous period was on time and had a normal pattern of bleeding or was it scanty. Also, whether you are a sexually active individual, and if so whether any chances of pregnancy could be there? If there is any such doubt, it would be advisable to take a home pregnancy test. Sometimes the scanty flow of implantation hemorrhage could be confused with a normal period and the actual bleeding could be a sign of threatened miscarriage.

If pregnancy is ruled out (by checking urine pregnancy test or if not sexually active), the hormonal disturbances of thyroid or prolactin hormones, and sometimes lifestyle-related problem that is PCOS also can cause such irregularities in periods. Also, stress can be one of the reason for hormonal changes and thus causing disturbances in menstrual patterns. Basically, this is suggestive of anovulatory cycles. So to find out these, you need to take certain blood tests. I would like to know if you had any recent weight loss, or do you face frequent acne and unwanted facial hair growth problems, any headaches or visual problems? These symptoms may provide some clues to the underlying problem which is causing a delay in periods for you. Please revert back to me with the necessary details for discussion, so as to find the appropriate cause for your problem and start the necessary treatment to control the bleeding.
