I suffer from severe pain in my periods. In June, I got an ultrasound and was diagnosed with endometrioma in the left ovary. I was on Ovaral G for 8 years as I suffered from dysfunctional bleeding when I was 21. Since 2-3 cycles, I suffer from fever during my periods and I have also developed lower right sided pain. Earlier, the pain was confined to left side mostly as I have a cyst in the left ovary, now the pain occurs in the right side also and continue till the last days of my period.
