Period or not

I had bleeding and lasted for 5 days and the first 3 days was heavy and the remaining 2 days got lighter. And yesterday I still have a very light bleeding.

Question:

1. Is that already my period?

2. Can I be pregnant even if I bled for 5 days?

Sorry if some will think its dumb to ask about this But Im overcoming a pregnancy scare

Thankyou!
