My wife had vaginal discharge of pinkish and brownish color, during ovulation period. After which we consulted a gynaecologist, who asked us to get ultrasound done as the doctor suspected PCOD ultrasound report showed no signs of PCOD but the endometrium was mentioned to be thick (size 17mm). Can you please help us understand if this is within normal range? Should we wait for her next period to see if the endometrium gets shed and reduces to normal size? Last period was on 22nd Oct.
