TMI AM I Going Crazy? Is this abnormal?

Is this abnormal or is there something with me should I be worried. Okay so it's 5 days before my period is supposed to start and I get a good a amount of discharge every day ,but it shows up a light yellow tint on my underwear. On my finger it appears white. So would it be white. It's more of a white a little thick when it's not so close up to white. But on the panty liner its a yellow color. Idk really nervous
