(TMI PIC) tiny pink spot in cm

So I'm 11dpo, haven't really had many symptoms, 9/10dpo I had a weird not painful pulling kind feeling in the uterus area, was on/off all day 9dpo and ended the evening off 10dpo.
I'm now 11dpo just went to the bathroom and I notice a tiny pink dot while wipe... (Sorry girls) 
What do you think? Could it be implantation? I don't know.
Thanks lovelies x
