Wtf is happening!

𝔫𝔦𝔠𝔬𝔩𝔢⚢︎✰

Ok, so I thought I just finished my period, but today I felt something wet down there, and I see brown blood. It smells like iron, not that gross period blood smell. It is also my 2nd period ever. I'm only 13. I also actually had blood and cramps and shit this time. I am freaking out, because I started my period on February 1st, and today is the 8th. What is happening and what should I do? 😭
