Welcome to HealthcareMagic, Depot shots should be taken on time or at least within 2 weeks of the scheduled date. As you have missed depot shot, if you had unprotected sex then it may be possible that you are pregnant. My advise for you is to wait for your menstrual period. If you get your period then you are not pregnant. But if you do not get your periods then do a early morning sample urine pregnancy test to know about your pregnancy status. Hope that answers your question. Have a good day. Regards, Dr.Imaad.
