My period came on 2 days early. My breast are tender and big and Iam always eating I never get full could I be pregnant

Chances are that you're not pregnant. You got your period. Your period can and will often come early or late. That's not a symptom of pregnancy. In fact, getting your period would indicate that you're not pregnant.

Eating more, breast tenderness, those are all symptoms of pregnancy, but also of PMS.

I'll go out on a limb and say that you're not pregnant, but if you believe you are then the only way to confirm it is to take a pregnancy test. We can only guess.

If it is a regular period, not just a one day spotting or light, most likely no you are not pregnant, Most women do not have their period exact every month, so illness, infections, stress can all alter period times
