My menstrual cycle skip two months. Please don't answer you must be pregnant 🤰 because I am still virgin and I am 21 years old.My last period was February 21 , 2017 and my period did not arrive on March at all . Now it April 15 and no sign of my period coming. What should I do. I am used to my period skipping a month because it comes twice the next month. However this the time it is skipping two months and I am not why or how to react .
