I started my period 5 days early but its brown and lighter than normal. It's going on day 5 of this flow now and it's still the same. I thought brown period blood was old blood. Should I be passing old blood for a week? I've never had a period this light before, it's really weirding me out. I had terrible cramps when usually I dont have many PMS symptoms (I'm on the pill) and idk, I guess I just want someone to say it's normal to have a weird period. 😅
