No, why take a medication if not needed. My best advice would be to wait for the first symptoms of GSM and that's usually a burning feeling after sex and the symptoms of a UTI. Once that happens start on treatment without delay, it will be for life.
When I started to suffer with GSM symptoms at 70 I had no idea what was happening to me, now its talked about freely on TV and treatment is easily bought over the counter for women over 50.
