My period came a week early and only lasted 2 days could I be pregnant. Last week I had sore breast that now just feel super heavy and was very tired all the time.

Bleeding during pregnancy is possible. If you got your period, then no, you're not pregnant. The thing is, many women that bleed throughout their pregnancy, mistake it for a period. In other words, there's no way for us to know if your period was just early, and a bit off, or if you're pregnant.

Only one way to know if you are or aren't. Wait until your next period is due. If you miss it, try a pregnancy test using first morning urine.
