CM? Could this be a sign of pregnacy?

I'm 13dpo, and been having A LOT of clear watery sticky cervical mucus for the last 2 days. I never get this before af and I'm having no pms symptoms at all and I always do before I start. Has this happens to anyone else and ended up pregnant?

I know it's not a for sure way to determine pregnancy, just want to know if it's happened to anyone else. Thank u
