Every month discharging same like egg yolk white. What is that?

Possible yeast . If you are having a white discharge at time of your menstrual period, you may be having a yeast (monilia, candida) vaginal infection. Do get evaluated, since treatment may be simple. Treatment may be more difficult if you have diabetes or have recently been taking antibiotics. Hope that helps. .
Normal CM. That is a normal cervical mucous after ovulation. Dont worry. Clomid (clomiphene) is bringing on ovulation.
