My last period started sept 2nd, i took a pregnancy test oct 23-negative, i want to take two more tomorrow to make sure, i havent had any symptoms, my partner also didnt even finish but my period has never been this late, not sure what to do?

Some thoughts...: In a woman with regular periods, some causes of a late period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc… Pregnancy is a common cause of a missed period, if sexually active. Urine tests are very accurate by 3 weeks after sex. If worried, can call Dr. via video.
