I'm 13 and I just had sex for the first time, but we didn't use protection. I was on my period when it happened but after that I been spotting. Could I be pregnant?

You didn't use protection, so yes you could be pregnant.

Get a test.

Oh, dear.

Sexual education is lost on so many young people.

Yes, pregnancy can occur at any time when you have sex - even with protection there is a small chance. STDs are also possible, so you really should protect yourself in the future. Don't make this mistake again.
