HI, thanks for using healthcare magic
One of the treatment protocols for PID involves the use of the doxycycline for 14 days as you have used. This is combined with a medication called ceftriaxone
which is given as one shot at the beginning, in some case one other tablet may be order as well.
The discharge may be due to continued PID which may require additional treatment or due to a yeast infection. The use of antibiotics can result in yeast infections
which cause yellow white discharge and pv itching.
If it is not possible to get an earlier appointment, you may want to consider visiting your local pharmacy for a topical treatment for candidiasis
to see if it is contributing to the symptoms.
hope this helps
