Am I having brown implantation bleeding?

Leyla • TTC #1 Polycystic Ovaries

Hey girls really need your help. Basically I’m 7dpo and I’ve had brown bleeding? It’s a tiny amount in my knickers and when I wiped was a little on the tissue and now its just completely stopped today. Yesterday I had it also once but just in my knickers the a little amount. Do you think it’s implantation bleeding? my period is due in 4 days.
