Weird period??

Morgan

So I got my period Monday 2 weeks ago, it started out really light barely there spotting up until Thursday when it turned into a normal like period. And I bled all the way up until the next friday. And now tonight I started bleeding light pink again?? This has NEVER happened before and I’m so confused. What could this be? I’ve been having unprotected sex but idk if this is anything to do with a pregnancy
