Thanks for the query to H.C.M. Forum.
Don't take tension as note down the side effect of Cerazette
beside others as,
Changes in cervical secretion,
increase in the size of firbromyomata,
aggravation of endometriosis
aggravation of certain vaginal infection
As you stated that milky discharge without smell i.e this is cervical secretion without any infection.
If you are feeling uneasiness then stop the drug ,other wise you can continue it .
