OMG is it getting closer?

OKK so I have many other questions about my period but today instead of getting a little bit of discharge on and on through out the day little by little and got two big ones. In the morning it was really oooy and white and thick and there was a lot then in the afternoon I got another one. I am 13 my sis has gotten her period around this time going tinto grade eight and I have another sister. That's all PLEASE NO GROS COMMENTS THIS IS NATURAL GIRLS/WOMAN ONLY PLEASE.
