AF or Implantation??

Katie

Hi everyone, please can you help? 

8dpo I started to spot, had 3 days of spotting and now 11dpo. 

Weird thing is it's not like my normal AF, it's all dark brown clots and nothing else (I.e. Not clots and discharge, just clots) 

I read clots are unlikely to be IB, but there's no red like my normal AF either. 

Any ideas? 

Thank you
