Spotting

Jada

So I’m currently 10 dpo and I woke up with some spotting on my underwear this morning. It’s been mild since then but it also has brown and sticky clear stuff. I’ve been googling about it all day and I heard it could be implantation bleeding but it could also be my period so I’m not sure. Oh and I’m not due for my period until the 21st. Any suggestions on what it is?
