Most of the medication will be dissolved in the vagina but will not be completely absorbed by the vagina in the process of insertion and the residue that is not absorbed by the vagina will flow out together with the vaginal discharge. It is better to insert the pills at night. You should not be too nervous after the yellow discharge, you should wash it in time, you can use pads and change them in time. Some of the medications are yellow in color and are melted into the vagina. The yellow discharge will decrease significantly two to three days after the pills are inserted.
