My First Period

Hi,
I’m 13 years old. I just got my first period yester had been wearing liners for a week, because of discharge but that morning I was like, nah, it won’t come why waste a panty liner?
It was 10:30 in the morning. I was at my grandmas in the countryside. I only had two pads and another 24 hours.
I had cramps all morning but for once was conviced that it was my stomach, not my uterus. I was obsessed with getting my period for over 4 years.
So I had done really piles of research and these scam quizzes “When will I get my first period?” Which that same morning said in one year, and I was conviced I was ready.
I went up to pee, and saw a big, brown spot on my underwear. I was in denial. I was happy, I couldn’t lead myself to believe it. But I got up, took a pad from my bag, went, texted my mom, who was, by the way, very happy, and told my grandma who went to a friend to a so for pads.
