Well I am about 5 days away from my period and I have a lot of brown discharge and I can't stop eating so could someone help me please

Any fertile woman who has sex can get pregnant.
A brown discharge is 'old' blood exposed to air, and is common.
Eating more is common enough, as hormones fluctuate wildly.
I suspect that you are getting your period early, but you can be pregnant and have some bleeding, and you can be pregnant and miscarry early (so small you might miss the embryo), so there are 3 scenarios.
Since you are here worried, have you a good method of birth control (pill, patch, IUD)?

Well it is pinky brown

As joypulv stated, it might be that your period is about to start. Many women will have an increase in appetite right before and/or during their periods. Brownish discharge can also be common right before a period starts or at the end of one.

Give it another couple of weeks and see if your period comes on. If no period, try a pregnancy test.

Menstrual fluid/tissue can be red, pink, brown, super dark reddish or brownish clots, thin, thick, clumpy, light, heavy.
It can vary from month to month and year to year and woman to woman.
So can when you get your period, regardless of how regular you have been.
Appetite, fatigue, backache, tender breasts and sensitive nipples, mood swings, and so on can be signs of your period, being pregnant, coming down with something else, or nothing at all.

None of it is an indicator of pregnant or not pregnant.
The ONLY one is a pregnancy test.
