Period getting lighter with age?

Lauren

I have no idea what this means but my period flow has lightened up considerably since I started menstruating. In my teens and 20s it was VERY heavy. Now I barely ever even have to use a “regular” tampon, light tampons are often enough. I’m 35, have a paragard and take spironolactone for hormonal acne. I thought paragard usually makes one’s flow heavier but I’ve had the opposite happen to me, if anything. I’m worried this could be a symptom of early pre-menopause? Or maybe it just means I’m super healthy 😂 I have no idea. Anyone have the same experience or know what could cause this? I talked to an ob-gyn and she just said I was lucky lol
