Hie doctor, lm trying to conceive but to no avail. I am not on any family planning method at the moment. But my menstrual cycles are unpredictable. Sometimes they come back after 10/12days. Like now my last period was on the 10th of April 2016 but today 23 April l work up with cramps and a some blood on my pants. What could be the problem. And what must l do to regulate my mps
