I'm supposed to enjoy my length on the 31st, when should I start wearing a napkin?

I just started my length a month ago, I think.I'm supposed to enjoy my length on the 31st, when should I start wearing a napkin?
Ummm... when it starts.
a couple of days since... or when you start to feel your are starting to own cramps
when your young your cycles will customarily vary so a afternoon or two before or when you start to spy those subtle signs just wear a panty liner, and maintain a pad handy similar to purse or locker, Hope this helps!
i'd speak the 30 just within case it comes impulsive
Dear, chances are you won't gain it on the 31st.
