Warning - Picture. Is this implantation or start of AF?

[iiTTCii]

I'm 12 dpo and I've been having stomach cramps. I've just been to the toilet and wiped and got some CM mixed with brown. As this is my first month ttc, I haven't taken much notice in the past on how AF starts.
AF is due Tuesday.

CM has been clear since.

I have that the moment but sometimes it's pink not brown, had it for 2 days with cramps on and off
This normally means af is going to come on for me

But it could be different for you, fx for you

 

[iiTTCii]

Yes, I think I might be kidding myself. I've been making a point of wiping before and after when I've been to the toilet and nothing else since.

Could be IB or the start of af. It all depends.

Thats a hard one given that you are 12dpo. Id say keep thinking positive! I did have IB with my daughter and it was light pinkish brown, and I only got it once - 5 days after my BPF. (scared me to death) Good luck!
