My first period

My first period happened about a week ago when I was on a family trip in the mountains. I was just in my room when I suddenly had to go pee really badly, so I went to the bathroom. When I looked in my panti liner, (I have them for discharge) there was the tiniest red spot. I didn’t think it was my period, I thought it was just spotting. Then, I wiped and there was blood. I looked in the toilet and there was blood there, too. So I texted my mom and we bought some pads and tampons. (Tampons because I’m a swimmer…but my first period ended before the practices or the meets) The whole thing lasted for about 5 days. It’s really nothing to be afraid of. Btw I’m 11.
