I feel like my period is coming and not coming.

Menstruation delay, first of all need to rule out whether pregnant, need to go to the hospital for hcg examination or use test paper for testing; if it is clear that there is no pregnancy, you need to carry out B ultrasound examination, to determine whether there is abnormal endometrial thickness or abnormal hormone secretion, by taking estrogen and other ways to urge menstrual cramps.
