I’m new please help!

So I got my first period about a month ago (I am 14) and I got told u get ur second one a couple months after. But then I though I got my second one yesterday, BECASUE there was blood in my underwear and a bit when I wiped.So I put in a pad for the rest of the day and nothing came out and then I also did for overnight but still nothing. Is it normal? Was that my period? Was it a one day period? Please I’m so confused
