NEED INFO!! ASAP

Ok so I thought I started my period a week early, but it's not at all like normal. Normally I bleed light to medium and its red. And I usually want to eat, have cramps and have attitude problems. But this time it's a week early like I said and its been light pink and brown the whole time, no cramps, no hunger, attitude or anything. And I got to reading up on the symptoms and it said it could be implantation but idk. What do y'all think??!
