Thanks for posting on HCM,
The antibiotics are good if we only consider that the cause of the infection is of bacterial origin but they are other microbes that are not bacteria that can cause itchy and foul smelling vaginal discharge
such candidosis or even parasitic infections which can complicate to PID. So saying, your treatment might need to withdraw amoxicillin
from your antibiotics which promotes vaginal yeast infection or candidosis, hence further vaginal infection
It will be best at this point to take sample of the discharge and do a laboratory analysis to identify the pathogenic germs that are present and that maybe responsible for your vaginal infection hence PID. If you are having problem of conception, this might mean that the PID must have caused severe tubal patency, hence inability to conceive. You might require surgical intervention if antibiotics fail to deocclude your tubes.
I am afraid you will only have to rely on your gynobs for further management. You need to exercise some patience as treatment of infertility
can take time and can be complicated too.
Hope this help and God bless you too.
