For the past 6 months i have been experiencing period like cramping about a week before my period is due and for the past 3 months i have also been experiencing a slight sharp pain which feels like it is coming from the left side of my womb around the same time as the early cramping, it is not extremly painful but it is uncomfortable and i am wondering if anyone would know what could be causing this, i am worried as i think i may have ovary cysts or something, some advice would be greatfully apreciated thanks
