I was dignosed with overian cyst few years back then have a surgery for cyst removal in 2013. Now for the first time in my whole marriad life i missed my periods for 15 days by now. But my pregnency test is negative. I went for an altrasound and have a cyst in my left ovary and fibroids. I am confused about all the situation. What should I do. Plz advise me.
