period??

Today is my first day of my period (Two days late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>) and at first the blood was brown and very liquidy. Does this blood look normal? this period definitely feels a lot more different and painful than previous periods. There's barely any blood coming out but it feels like its a lot, like its soaking through the bad and the blood looks really really liquidy than usual and I'm having severe cramps
