What’s going on 🤦🏼‍♀️

I’m on CD 20, not doing OPK’s this month (go figure) and I woke up this morning to bleeding. I literally just got off my period two weeks ago and I normally don’t get my periods until around CD 32 or so. Any idea what it could be? I’m leaning towards AF but I’m having no cramping and I’ve never bled this early. I’m so frustrated 😭
