need help

Amber
Hey ladies, l woke up this morning to red/brown discharge 10 days before my next period. My fiancé and I have unprotected sex and I'm not on any birth control. I've been googling it and it says it's most likely implantation. My last period was 1/16-1/20 and we've had sex from 1/22 to two days ago. 
Can someone please help me figure it out?
