Basically the discharge was most probably due to atrophic vaginitis .
This is when , after menopause, due to estrogen deficiency, the endometrium and the vaginal mucosa all thin out and break out, becoming increasingly fragile and prone to infections, cracks and bleeding. Hence the discharge, which responded favourably to estrogen treatment locally.
There is no problem in using the pessaries as long as you wish, upto a period of even a couple of years.
The clear white discharge could be normal vaginal discharge, as the lining improves in response to the hormones ( same as you experienced physiological normal discharge during the reproductive years ) .
As there is no odour and no itching, it signifies that this is not due to an infection, or due to hormonal imbalance.
So to answer your questions specifically.
- Yes, the clear discharge is most likely a result of the estrogen pessary.
- continue taking the pessary in the frequency and dosage prescribed to you by your doctor as long as there are no undesirable side effects , even then titrate the dosage only on medical prescription
- No, i do not find anything worrisome in your symptoms.
All the best to you, and please feel free to ask any further follow up questions , or ask for any clarifications anytime.
