TMI topic: "watery periods"

Mi
Hello ladies, long time no posting, but I'm very concerned. I have been having my cycle every month (yes normal) either a day before or the day of that glow predicts. Although everything seems to be normal, my cycle has been "watery" lately. No clotting or VERY LITTLE! I am 20 soon to be 21 and I am sexually active. Any advice you can give, would be helpful, thanks in advance ❤️😘
