Hi. I had endometriosis on both ovaries and tumor on my right ovary and 10 cm chocolate cyst. I had lap done (at the age of 19) and my right ovary was removed. Since than I was taking Yasmin pills (they are ok, because there aren't any unpleasent and serious side effects). But, because I have problems on my left ovary, too I had to do another lap, but I didn't want to, so I went to a puncture (they sucked the cysts and the blood).
