Could I be pregnant

Symptoms I have had the past 3 days my period isn't supposed to start till the end of next week.

1. Eating all day. Eating weird things.

2. Period like cramping.

3. White creamy discharge.

4. Very strong vaginal odor.

5. Feeling fat.

6. Feeling tired.

I think I'm having implantation cramping. But I'd for sure. It all feels the same as period cramps. :(

Could these be signs of pregnancy.
