Need help! I'm confused

Karla • Wed, Dec 03

So like I got my period 4 days earlier than usual. Before I start my period I usually get sore breast like a week before and I didn't. And I started and had no cramps! I usually do! It lasted for like 4-5 days and just disappeared. When I have the last few days it turns light brownish color but it didn't! I just disappeared. And I'm a bit worried!!
