Success Without Interventions?

Are there people here who have had success without making any significant changes or taking things like progesterone or baby aspirin? I’m curious because many people experience unexplained miscarriages and are often advised by their doctors to just keep trying, as it will eventually work out. Have any of you found success simply by continuing to try, without additional interventions?

I often see success stories where people mention things they’ve done, like taking progesterone or trying other treatments. But I’m curious are there people who didn’t make any of those changes and still eventually had success? I’d love to hear from those who just kept trying without interventions and it worked out for them.

Thanks!!
