Early period?

somebody

I am a college student. I was really stressed out over this project for the past week and finally got it done. My period decided to come 4 days early. But it was really light, and light colored. Went to bed shortly after I got my period, and woke up went to the bathroom it like nothing happened. My period was gone. Is this normal? Because I was stressed out? Also, I have been taking CBD gummies and I am sexually active.
