Hi, am 26years, saw my period last on the 29th of may and the due date for my next expected period was on the 26th of June 2017 but am yet to see it. Before the due date of my expected period, I was on yeast infection treatment which lasted for 6days but my period due date was on the 3rd day of the yeast treatment. Now, I get so very weak and lazy, got sore breast, and feels strange most times. Pleas what could this mean? th of may and the due date for my next expected period was on the 26th of June 2017 but am yet to see it.
