Why haven't i gotten my period?

You get the most from this site when you provide background information with your post. Sexually active or not? On BC? Regular cycles before? Data matters. Some otherwise regular women occasionally skip a cycle or two. After 60-90 days many docs offer meds to bring on a cycle if the pregnancy test is negative. If the delay is from pregnancy, the simple urine pregnancy test is likely positive.

If you had sex you may be pregnant. Menstrual irregularities are not uncommon and anovulatory cycle is a common cause. If you miss more than two periods it would be time to see your doctor. If you do not wish to be pregnant, use contraception all the time. You may consider implanted contraceptive or an IUD. http://www.nichd.nih.gov/health/topics/menstruation/conditioninfo/Pages/causes.aspx
