Implantation Bleeding?

Mara
Hi ladies! So I am 12dpo and when I woke up this morning I had a few browning pinkish streaks on my undies... I never spot before AF, ever. I'm just wondering what you all think? I hope it is IB. I've had some other symptoms too but let me know what you think. There wasn't any when I wiped but these tiny spreads in my undies...
