Were ur periods regular before this. Is there any chance of pregnancy. If yes then U need to do Urine Pregnancy test. It should be done 10 days after missing your period. For example if your date was 10th, then do the test on 20th. Before that it can give false negative or false positive test. So u need to wait n repeat test If no then Get ur thyroid profile, CBC, FSH, prolactin, blood sugar fasting checked from some lab. If everything is normal then do an ultrasound of abdomen. For more details u can consult me.
